Symptoms
A growl that changes with speed or while turning, play when you rock the wheel at 12 and 6 o'clock, or an ABS light from a damaged sensor.
The fix, step by step
- Lift the corner and remove the wheel, caliper bracket and rotor.
- Unplug the ABS sensor, remove the axle nut and the three hub bolts from the back of the knuckle, and pull the hub (it may need persuading).
- Clean the knuckle face, fit the new hub, and torque the bolts and axle nut (Northridge4x4: 75 ft-lb hub bolts, 100 ft-lb axle nut).
- Mopar lists different hubs for 2007–2010 and 2011–2018 JKs, so order by year.
Tools & part numbers
- Large axle-nut socket
