Overview
The Crown Automotive J8126510 is a spindle bearing kit for the Dana 30 front axle, fitting either the driver or the passenger side. It is a direct fit for the 1972-1976 CJ5, the 1972-1975 CJ6 and the 1976 CJ7.
The spindle bearing sits where the front wheel spindle meets the axle, and this kit gathers the bearing parts for that location. Check the package contents against your installation before starting.
The three models on the list are the middle-era CJs, built between 1972 and 1976.
Spindle bearings carry the front wheel load on a Dana 30 axle, so they are a wear item on older Jeeps that see regular off-road use. Replacing them as a kit is the usual approach when the old bearings have started to show wear or play.
Crown describes itself as a maker and distributor of replacement parts for Jeep vehicles, including many factory-discontinued items.
One kit works on either front spindle, so it is not left-hand or right-hand specific. Match the kit by part number and by the models below before ordering.

Before you buy spindle bearings
Spindle bearings carry the front wheel load and let the hub turn freely on the spindle. On an older Jeep that sees regular trail use, they take constant side loads from rough ground, so they tend to wear gradually. A worn bearing often shows up as play when the wheel is rocked at the top and bottom, a grinding or humming noise that changes with road speed, or uneven tire wear.
Bearings rarely age alone. The seals, the hub and the spindle surfaces wear alongside them, and a damaged seal lets dirt and water into the new bearings. Inspect the spindle for scoring and rust while the hub is off, and replace seals whenever the bearings are changed. Clean the bearing races thoroughly and pack the bearings with fresh grease before fitting them.
- Check the spindle for scoring before fitting new bearings
- Replace the seals whenever the bearings are changed
- Recheck wheel play after the first few trail runs

Vehicle fitment
The kit fits three model lines with narrow year ranges, so the match depends on both the model and the build year.
The manufacturer fitment list for part J8126510 covers: 1972–1976 Jeep CJ5; 1972–1975 Jeep CJ6; 1976 Jeep CJ7.
Not listed: the CJ5 before 1972 or after 1976, the CJ7 after 1976, and the Wrangler. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the kit works on either side, one part number covers both front spindles, though each side needs its own kit.
