Symptoms
Grease flung around the inside of the wheel, or a click on full lock under power.
The fix, step by step
- Support the truck, pull the wheel and the hub, disconnect the lower ball joint or knuckle as the manual describes, and slide the axle out of the differential.
- Either rebuild the joint with a new boot, clamps and grease, or fit a complete replacement axle.
- Check the differential output seal while the axle is out.
