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”.
