Can't keep steer tires on Pete 387

[flight0801]

I've got a 2007 Pete 387 and can't keep tires on it. Have had it aligned 3 times and can't seem to keep steers on it, only getting about 2 months out of a set of tires. [smilie=real mad.gi:

I'm told by alot of other guys they're having the same problem, my question is...has anyone found a solution? Maybe one particular BRAND of tires that tends to last longer? It has been suggested to me that I switch to Michelins, and I don't mind doing that and paying the extra if I can justify it by better wear.

Anyone have experience with this?

Thanks

Do the tires wear out or start shaking ? 2 months ? They should give you new ones.

If it's a shake, then it's run out. The bead is not sitting true with the rim. I'm sure they checked that. If you look at the side wall close to the lip of the rim. You will see a line. Check to see if that rubber line is the same all the way around the rim. If the line is not even with the rim it not up on the flat seating area of rim. 2 months like that will make a steer junk or at best a trailer tire.

Just a guess.

[Mr Bee]

Try a different alignment shop. Let them see the tires before you replace them. Some places will give it a visual and give you an idea as to what the problem is.

Could you give us some insight as to how the tires are wearing, and the type of roads you are running?

[Maxx]

More information would help.

I don't think changing brands will fix your problem you've got some underlying problem with your suspension or ???

I had a problem with premature wear and scallops on my trailer tires. A tire shop was able to diagnose the miss-aligned trailer axels as the cause. Since the trailer suspension was repaired and aligned the tire wear has been good.

[dynoman]

My guess would be shocks as well. Know people who have had same problem. Changed shocks and fixed. Pretty cheap fix too.

[flight0801]

Thanks for the suggestions guys. Appreciate the help :)

[Mercenary]

Here is a thought....

Have you had the wheels checked? Might be one is cracked or warped enough that it is causing all your issues.

[hotshoe36]

Changing to Yokohamas fixed the wear issues on my Volvo, after everything else had been checked/repaired/replaced.

[Franx]

Shocks wear out??

[Mr Bee]

Loose wheel bearings will also cause irregular tire wear. Manufacturers now recommend using a torque wrench set at 35 ft/lbs.

Seems to me that they'd run hot if you did that.

My last Kenworth was somewhere around 650 ft/lbs. on the front wheel bearings.

35 ft/lbs on your wheel bearings, as per Mike Becket, owner of MD alignment. He spoke of that very issue last Thursday.
I worked with a carrier a few years ago running the parts department, and a bearing manufacturer told us to start using a torque wrench on wheel bearings, and to no longer spin the wheel while tightening. Exactly the same info Mike Becket was talking about.

I could have heard him wrong, as 35 ft/lbs does seem a little light. I will send him an e-mail to confirm.

[Pipeman]

I could have heard him wrong, as 35 ft/lbs does seem a little light. I will send him an e-mail to confirm.35 is very little. You wouldn't need a torque wrench with a 3 to 4 foot handle to get that. Heck, a 1/2 ratchet should do it.

[TimTheTrucker]

650 sounds way to high to me. I have watched mechanics install bearings, and never seen them use a torque wrench long enough to reach 650

[ralph]

650 sounds way to high to me. I have watched mechanics install bearings, and never seen them use a torque wrench long enough to reach 650

I'm with you, wheel nuts aren't even torqued to 650 lbs.

[Pipeman]

I am making my reference towards Steering Axle Bearings as that's what the post is about.

I recall when my truck was brand new and had a leaking wheel seal on the left steering. I questioned the torque rating and was told that due to that design of eaton axle the rating was damn high. I'll talk to KW tomorrow and verify.

[ralph]

If you google "steer axle wheel bearing torque" and go to the first topic on the second page it is a PDF file for SPICER. If you scroll down and read page 5 of 11 it gives you the specs for Dana Steer Axles. 250-300 foot lbs is the magic number for the inner nut, the outer nut is torqued to 200 foot lbs plus or minus 50 foot lbs.

I'll get the specs for the Eaton Axle. 35 pouns is about what the specs for my wifes Toyota call for.

[canuck in da truck]

you dont want any preload on your bearing or they will burn up--if you dont rotate while adjusting you are risking a chance that bearing isnt seated in race properly--initial torque ball park area is around 200 ftlbs then backed off --and checked with dial indicator--.001-.003 ens play is what you want--as stuff does tighten up a bit when it heats up---every axle has their own little nuances---we always had the procedure for each type on the wall--the nice big free posters

[Mr Bee]

Here is a link to the Stemco bearing adjustment proceedure.

[Pipeman]

Phone KW this AM and they said that on my KW Eaton steer with the crush sleeve, 350 ft/lbs.

.

4. Install the inner spindle nut with dowel pin outward and tighten. (see Figure 6)
5. While rotating wheel end, torque the inner nut:
• Steer Hubs 250-300 lb. ft. Do not back off.
• Drive Hubs 300-350 lb. ft. Do not back off.


That's a hell of a lot more than 35 ft/lbs.

LMS™ HUB ASSEMBLY INSTALLATION ONTO SPINDLE PROCEDURE
1. Inspect the spindle and nut threads for corrosion and debris, clean thoroughly or replace as required.
2. Mount the hub assembly onto the axle spindle with a smooth, firm motion. Use care to maintain alignment
between the bearing cones and spindle and to avoid seal damage.
CAUTION: Never support the hub on the spindle with just the inner bearing and seal. This can damage the seal and
cause premature failure.
Note: When installing a complete wheel end assembly, a wheel dolly is required during installation to make sure that the
wheel seal is not damaged by the weight of the hub, drum and tire.
3. Remove the installation tool from the hub assembly.
WARNING: Do not mix spindle nuts and lock washers from different systems. Mixing spindle nuts and lock washers
can cause wheel separation.
4. Install the inner spindle nut with dowel pin outward and tighten. (see Figure 6)
5. While rotating wheel end, torque the inner nut:
• Steer Hubs 250-300 lb. ft. Do not back off.
• Drive Hubs 300-350 lb. ft. Do not back off.
6. While rotating wheel end, torque the inner nut:
7. Install the dowel type washer onto the axle spindle-aligning tab with keyway. If washer does not align with
dowel pin on inner nut, remove washer and turn over and reinstall. If after this, washer still does not align
with dowel pin, tighten inner nut just enough for alignment. Never tighten the nut more than half the distance
between the holes.
CAUTION: NEVER back off the spindle nut to align dowel pin with dowel washer.
CAUTION:

[Pipeman]

If you want to give me your email addresses, I'll email the pdf file to you.

[TimTheTrucker]

Sounds like a big long torque wrench would be required, but I wonder do some truck wheel bearings require less torque? When I have watched mechanics install wheel bearings, they did not use a torque wrench, just used like a breaker bar arm wrench, and then tightened and loosen while spinning the wheel until it felt just right. It was quite a complicated looking procedure.

INSTALLATION PROCEDURE

The following service procedures apply to the wheel end assemblies of the Dana steer and drive axle models listed. Follow
these service and assembly procedures carefully to obtain proper wheel bearing adjustment and to increase service life.


WARNING: Never work under a vehicle supported by only a jack. Always support vehicle with jack stands. Block the
wheels and make sure the vehicle will not roll before releasing the brakes.

IMPORTANT: Wheel seals can be easily damaged during handling. Leave the seal in its package until installation to
prevent damage or contamination.

LMS™ HUB ASSEMBLY BUILD UP PROCEDURES:

1.
Inspect/Clean the hub cavity, spacer, and bearing bores for any contaminants.
Important: Lubricate the wheel seal, and inner and outer bearing cones with the same lubricant used in the axle sump for
drive wheel ends or lubricant to be used in hub for steer axles.


CAUTION: When using an oil bath system, do not pack the bearings with grease. Grease will prevent the proper
circulation of axle lubricant and may cause wheel seal failure.

CAUTION:
For steer axle hubs, install the bearing spacer into the hub assembly with large diameter end facing the
inner bearing cup. This must be done before bearing and seal are installed.

2.
With hub or wheel end assembly placed in a flat position, lubricate the inner bearing and install cone into the
inner cup of the hub. (see Figure 1)
3. Place the seal on installation tool facing the proper direction. (see Figure 2)
Note: Do not apply any bore
sealant to seal O.D. or I.D.

[Pipeman]

Visual Inspection

Visually inspect for leakage and oil contamination.

1.
Check to see that no oil is present around the hubcap or on the wheel.
2.
Check to see that no oil is present on the hub, brake hardware, or brake shoes.
CAUTION: If oil is present investigate the cause and take corrective action.

3.
Visually inspect the lubricant for discoloration. Under normal conditions, the oil will darken slightly. A white
or milky appearance indicates water contamination. If the inspection indicates contamination, completely
service the LMS Wheel End. Use genuine LMS replacement parts.
IMPORTANT: Replace seals and lubricant every 500,000 miles.

SERVICING THE LMS™ HUB ASSEMBLY

The LMS™ Hub system is designed for extended service without any maintenance.

Since the LMS™ Hub system uses standard size spindle ends, the entire system is serviceable with the ability to re-build
with industry available components, should an emergency truck down situation occur. However, to ensure optimum
performance of the LMS™ Hub system, Dana suggests that the hub be rebuilt or serviced with the original components.

External Inspection 100,000 miles or Annual Inspection

Check the lube level and condition of the oil fill hubcap. If lube is contaminated replace lube with the same lubricant. If the
lube condition is good and the level is low, fill to the proper level. Check for any signs of leakage at the seal or hubcap
gasket areas. Check for soaked brake linings.

Take appropriate action if leaks or oil-soaked brake linings are detected.

Raise the vehicle and check for smooth rolling of the wheels. Check for tire cupping (not regular tire wear). Check for signs
of excessive endplay in the wheels-end. This does not include removal of the hubcap.


Note:
The semi-fluid grease will not show the normal spreading over the hub and brake components as hubs filled
with oil. When inspecting for grease leaks, the inspection must be done carefully with the aid of a bright light
from a flashlight or droplight. A slight weep or wetness of grease on the exterior of the seal is typical and
does not necessarily require seal replacement.


Note: If a gasket leak is noted, replace the gasket. If a seal leak is detected, remove and replace the wheel seal and
rebuild with original LMS™ components.

1.
Replace the wheel seal, hubcap gasket, and lubricant every time the hub is serviced or at 5 years/500,000 mile
intervals.
WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

July 2003 10 of 11
SHAIS146A


2.
Clean and inspect wheel bearings, cups, spacer and hub any time the hub is serviced or at 5
years/500,000 mile intervals and replace if damaged.
In case of emergency field repair, and LMS™ components are not available, the LMS™ hub assembly can easily be
converted to a conventional wheel end assembly. This can be done by obtaining the correct standard wheel bearings and
removing the spacer. When reassembling industry standard wheel ends, assemble per TMC RP-618.


WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

Operating Temperature

Check LMS Hub Wheel End as the vehicle enters the service area following a normal run. If the hub is running at a
temperature in excess of 150°F above ambient in normal operating conditions, service may be required.

Functional Checks

Note: Conduct the following inspections with the wheel (s) and drum removed.


WARNING: Never work under a vehicle supported by a jack without supporting the vehicle with jack stands and
blocking the wheels.

1.
Rotate the hub and check for free, smooth, and quiet rotation. If rotation is hampered, the LMS Wheel End
should be serviced immediately.
2.
Remove the hubcap, and install a dial indicator with a magnetic base on the spindle end.
3.
Check the endplay measurement by grasping two wheel studs across from each other on the hub. Pull and
push the hub.
4.
Record the endplay measurement.
CAUTION: LMS Wheel Ends should be serviced if endplay exceeds .006”.

LMS™ HUB ASSEMBLY INSTALLATION ONTO SPINDLE PROCEDURE

1.
Inspect the spindle and nut threads for corrosion and debris, clean thoroughly or replace as required.
2.
Mount the hub assembly onto the axle spindle with a smooth, firm motion. Use care to maintain alignment
between the bearing cones and spindle and to avoid seal damage.
CAUTION: Never support the hub on the spindle with just the inner bearing and seal. This can damage the seal and
cause premature failure.

Note: When installing a complete wheel end assembly, a wheel dolly is required during installation to make sure that the
wheel seal is not damaged by the weight of the hub, drum and tire.

3.
Remove the installation tool from the hub assembly.
WARNING: Do not mix spindle nuts and lock washers from different systems. Mixing spindle nuts and lock washers
can cause wheel separation.

4.
Install the inner spindle nut with dowel pin outward and tighten. (see Figure 6)
5.
While rotating wheel end, torque the inner nut:
•
Steer Hubs 250-300 lb. ft. Do not back off.
•
Drive Hubs 300-350 lb. ft. Do not back off.
6.
While rotating wheel end, torque the inner nut:
7.
Install the dowel type washer onto the axle spindle-aligning tab with keyway. If washer does not align with
dowel pin on inner nut, remove washer and turn over and reinstall. If after this, washer still does not align
with dowel pin, tighten inner nut just enough for alignment. Never tighten the nut more than half the distance
between the holes.
CAUTION: NEVER back off the spindle nut to align dowel pin with dowel washer.

CAUTION: When using LMS™ Hub, always install the identification tag.

8.
Install the identification tag onto the spindle over the outside diameter of the dowel-type lock washer, with the
anti-rotation bosses inboard and over the flats of the inner spindle nut.
Note: The identification tag is retained between the tang-type lock washer and the inner nut.

9.
Install the outer wheel nut on the spindle and tighten.
10.
Torque the outer spindle nut to 200±50lb. ft. (See Figure 6)
Note: If the washer tang and nut flat are not aligned, remove washer, turn it over and reinstall. If required, tighten the outer
nut just enough for alignment.


CAUTION: NEVER back off the spindle nut to align tang-type washer with spindle nut flats.


WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

11. Secure the outer nut by bending two opposing (180 degrees apart) tangs of the tang-type washer over two
flats of the outer nut on drive axle. Bend tang over on steer axles. (See Figure 6)
WARNING: Attempts to measure wheel endplay of the completed LMS™ hub system may result in false readings.
If endplay measurements are attempted, use a precision dial indicator. Apply a strong push on the hub
while rotating the hub back and forth. Work the hub until the dial indicator shows no additional
movement. Then apply a strong pull while rotating the hub back and forth. Work the hub until the dial
indicator shows no additional movement. Endplay measurements greater than .008” may indicate a need
to verify the correct components were used and the spindle nut was installed per the specifications.


WARNING: LMS™ hub components are made to special tight tolerances. Installation and/or servicing with other
components will either create excessive endplay or cause excessive pre-load, reducing bearing and seal
performance. Wheel separation may also occur.

12. Install new gasket on axle shaft flange for drive axles or install new gasket on hub cap for steer axles.
13. Install axle shaft on drive axle or install hub cap on steer axle. Tighten axle flange nuts or hub cap nuts to
specified torque.
14. Fill and lubricate axle and wheel ends with Dana approved synthetic lubes. (See Wheel End Lubrication
Procedure.)
Note: Purchase Genuine replacement Hub and Cup Assemblies through O.E.M.


WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

WHEEL END LUBRICATION



CAUTION: Before operating the axle, the wheel hub cavities and bearings must be lubricated to prevent failure.
When wheel ends are serviced, follow Dana’s wheel end lubrication procedure before operating the axle.

Steer Axles
Lubrication fill – Oil type wheel ends
Note: Wheel hub configurations vary, allowing different amounts of oil to be added depending on design. Allow for the oil
to seep through the outer bearing and fill the hub cavity.

Note: During this fill operation, do not allow the oil to go above the centerline or weep hole. This may result in a
weeping condition that may be perceived as a leaking hubcap. Continue to add oil until the oil reaches the oil level line as
indicated on the hubcap.

Center Fill Port:

1.
Hub mating surface must be free of dirt, burrs, and radial score lines.
2.
Hub mating surface, hubcap flange, and gasket should not be greased or oiled.
3.
Always install and reinstall a hubcap with a new gasket.
4.
Install the hubcap and tighten hubcap bolts to the specified torque.
5.
Fill the hubcap through the center fill port to the proper level
(between add and full).
6.
Rotate the hub several times then verify the lube is at the proper level.
Use only Dana approved synthetic lube.
Side Fill Port:

1.
Fill wheel end assembly through side fill port with the specified grade of oil.
2.
Install side fill hubcap plug and torque to 15- 25 lbs. in.
3.
Clean up any overspills that would give the appearance of a leaky hubcap.
Lubrication fill – Semi-fluid wheel ends

1.
Fill the hub cavity until the lube exits at the 3 and 9 o’clock positions of the outer bearing. This represents a 50%
hub cavity fill.
2.
Coat the spindle nut and spindle with lube.
3.
Place 2 oz of lube on the inner surface of the hubcap.
4.
Hub mating surface must be free of dirt, burrs, and radial score lines.
5.
Hub mating surface, hubcap flange, and gasket should not be greased or oiled.
6.
Always install and reinstall a hubcap with a new gasket.
7.
Install the hubcap and tighten hubcap bolts to the specified torque.
WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.

Drive Axles

Dana axles may be equipped with either of two wheel end designs:

• Wheel ends with an oil fill hole. (see figure below)
• Wheel ends without an oil fill hole. (see figure below)
Wheel Ends with an oil fill hole proceed as follows:

1. Rotate the wheel end hub until the oil fill hole is up.
2. Remove the oil fill plug.
3. Pour 21 oz. of axle sump lubricant into hub cavity through wheel end fill hole.
4. Install oil fill plug and tighten to specified torque.
WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

Wheel Ends without an oil fill hole proceed as follows: (see Figure 9)


5.
With axle level and wheel ends assembled, add lubricant through filler hole in axle housing cover until fluid is
level with the bottom of filler hole.(figure 1)
6.
Raise the left side of the axle 6 inches or more. Hold axle in this position for one minute.(figure 3)
7.
Lower the left side.
8.
Raise the right side of the axle 6 inches or more. Hold axle in this position for one minute.(figure 4)
9.
Lower the right side.
10. With axle on a level surface, add lubricant through housing cover oil filler hole until fluid is level with the
bottom of the hole.(figure 1)
Note:
Axles without wheel end fill holes will require approximately 2.5 additional pints of lubricant to bring the lube level
even with the bottom of fill hole.

Note:
For more detailed information, refer to Dana Wheel End Service Manual WESM-0060.


WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

LMS™ Hub Periodic Inspection and Preventive Maintenance

Along with normal pre-trip inspections and current shop preventative maintenance, Dana recommends a complete
inspection of the LMS hub during brake and or tire service.

Visual Inspection

Visually inspect for leakage and oil contamination.

1.
Check to see that no oil is present around the hubcap or on the wheel.
2.
Check to see that no oil is present on the hub, brake hardware, or brake shoes.
CAUTION: If oil is present investigate the cause and take corrective action.

3.
Visually inspect the lubricant for discoloration. Under normal conditions, the oil will darken slightly. A white
or milky appearance indicates water contamination. If the inspection indicates contamination, completely
service the LMS Wheel End. Use genuine LMS replacement parts.
IMPORTANT: Replace seals and lubricant every 500,000 miles.

SERVICING THE LMS™ HUB ASSEMBLY

The LMS™ Hub system is designed for extended service without any maintenance.

Since the LMS™ Hub system uses standard size spindle ends, the entire system is serviceable with the ability to re-build
with industry available components, should an emergency truck down situation occur. However, to ensure optimum
performance of the LMS™ Hub system, Dana suggests that the hub be rebuilt or serviced with the original components.

External Inspection 100,000 miles or Annual Inspection

Check the lube level and condition of the oil fill hubcap. If lube is contaminated replace lube with the same lubricant. If the
lube condition is good and the level is low, fill to the proper level. Check for any signs of leakage at the seal or hubcap
gasket areas. Check for soaked brake linings.

Take appropriate action if leaks or oil-soaked brake linings are detected.

Raise the vehicle and check for smooth rolling of the wheels. Check for tire cupping (not regular tire wear). Check for signs
of excessive endplay in the wheels-end. This does not include removal of the hubcap.


Note:
The semi-fluid grease will not show the normal spreading over the hub and brake components as hubs filled
with oil. When inspecting for grease leaks, the inspection must be done carefully with the aid of a bright light
from a flashlight or droplight. A slight weep or wetness of grease on the exterior of the seal is typical and
does not necessarily require seal replacement.


Note: If a gasket leak is noted, replace the gasket. If a seal leak is detected, remove and replace the wheel seal and
rebuild with original LMS™ components.

1.
Replace the wheel seal, hubcap gasket, and lubricant every time the hub is serviced or at 5 years/500,000 mile
intervals.
WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

2.
Clean and inspect wheel bearings, cups, spacer and hub any time the hub is serviced or at 5
years/500,000 mile intervals and replace if damaged.
In case of emergency field repair, and LMS™ components are not available, the LMS™ hub assembly can easily be
converted to a conventional wheel end assembly. This can be done by obtaining the correct standard wheel bearings and
removing the spacer. When reassembling industry standard wheel ends, assemble per TMC RP-618.


WARNING: Do not attempt to make LMS™ hubs by using LMS™ bearing, spacer and seals in a standard hub.
This may result in a seal or bearing failure, which may result in loss of wheel end and or loss of vehicle control.

Operating Temperature

Check LMS Hub Wheel End as the vehicle enters the service area following a normal run. If the hub is running at a
temperature in excess of 150°F above ambient in normal operating conditions, service may be required.

Functional Checks

Note: Conduct the following inspections with the wheel (s) and drum removed.


WARNING: Never work under a vehicle supported by a jack without supporting the vehicle with jack stands and
blocking the wheels.

1.
Rotate the hub and check for free, smooth, and quiet rotation. If rotation is hampered, the LMS Wheel End
should be serviced immediately.
2.
Remove the hubcap, and install a dial indicator with a magnetic base on the spindle end.
3.
Check the endplay measurement by grasping two wheel studs across from each other on the hub. Pull and
push the hub.
4.
Record the endplay measurement.
CAUTION: LMS Wheel Ends should be serviced if endplay exceeds .006”.

35 ft/lbs on your wheel bearings, as per Mike Becket, owner of MD alignment. He spoke of that very issue last Thursday.
I worked with a carrier a few years ago running the parts department, and a bearing manufacturer told us to start using a torque wrench on wheel bearings, and to no longer spin the wheel while tightening. Exactly the same info Mike Becket was talking about.

Did you check out the torque ft/lbs any further???
