Overview
The Crown Automotive J4004815 is a hub washer that installs after the inner nut. Hub washers sit between the nut and the hub assembly, so placement is part of the fit.
It fits the 1974–1983 Jeep Cherokee (SJ), the 1983 Cherokee Wide Track Chief, the 1984–1991 Grand Wagoneer (SJ), the 1974–1988 J10 and J20, and the 1974–1990 Wagoneer (SJ).
Key features
- Installs after the inner nut
- Hub washer type
- Fits SJ-era Cherokee, Grand Wagoneer, J10, J20 and Wagoneer applications
- Part number J4004815, also numbered CROJ4004815
Nut and washer stack
A hub assembly uses several small parts stacked in a set order, and each one has a job in keeping the hub tight on the spindle. Changing the order or leaving a part out can change the preload and let the hub work loose. Keep track of each part as it comes off, and set them out in the order they came.
Before reassembly, check the spindle threads for damage and clean the bearing surfaces. Use new washers when the old ones are bent or corroded. Set the nut to the torque in the service manual for your model, then check it again after the first short drive, since bearings and washers settle as they seat.
- Lay parts out in removal order
- Clean threads with a wire brush
- Recheck nut torque after the first drive
