Key features
- Outer pinion bearing cone for the 8.25 axle

- Fitment spans Jeep Wrangler, Cherokee, Grand Cherokee, Comanche, Commander, Liberty, CJ5, CJ7 and Scrambler, plus Dodge Dakota, Durango and Nitro
Cone wear and fit
The cone is the inner race of the pinion bearing, and its rollers ride on the cone surface as the pinion turns. Pitting, flaking or heat discoloration on the cone shows fatigue, and that wear can cause noise and play at the pinion. A cone should always be inspected whenever the matching cup is replaced.
Pinion bearings need correct preload to last, and that setting depends on the cone, cup, shims and crush collar working together. Keep the old and new parts marked so the shim stack can be reused where appropriate. Work on the pinion is best left to an experienced technician with the correct tools.
- Pitting or flaking on the cone surface
- Heat discoloration from overheated bearings
- Noise from the axle that changes with speed
- Play at the pinion flange
