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.
