Auto-Lock Free-Running Hub
Auto-lock Free-running HubREMOVAL AND INSTALLATION
Auto-Lock Free-Running Hub:
1. Remove auto-lock free-running hub assembly.
2. Remove snap ring.
3. Remove spindle washer and fixed cam assembly.
4. Install fixed cam assembly.
Be sure to align the tabs of the fixed cam assembly to the notches of the knuckle.
5. Place the spindle washer and then the snap ring over the axle shaft positioning them between the two locking grooves.
6. While supporting the axle shaft behind the knuckle, use an appropriate sized deep socket to securely seat the snap ring into the inner locking groove.
CAUTION: Visually verify that the snap ring is fully seated into the locking groove.
7. After installing auto-lock free-running hub, check operation.
During installation, apply recommended grease to the parts shown in the above illustration.
INSPECTION
1. Check axle axial end play.
2. Inspect fixed cam (thrust washer) assembly. If this part shows evidence of galling or heat damage-usually caused by too little axle axial end play-replace as necessary. Check axle axial end play if this part is replaced.
3. Inspect hub assembly. Hold inner splines on a finger and spin the outer body. If the hub shows signs of damage, or if there is excessive metallic clicking when the hub is spun, replace with a new one.
NOTE: New hubs are greased during manufacture. No additional grease is required.
New hubs are supplied with fixed cam assemblies.
CAUTION: Any hub, the original or a new one, should go onto the axle freely by hand and fit flush against its seat. If it does not fit flush, do not pull the hub into place by tightening the bolts. The hub is possibly misaligned inside and tightening the bolts will cause damage. Remove the hub and turn to align correctly before continuing.
4. Once repair is complete, test drive to check for correct operation and the absence of noise.
