What This Kit Helps Repair

• Rear differential bearing noise
• Gear oil leaks at the differential seal area

• Service issues on 10.50″ first-design ring gear rear axles
• Repeat repairs caused by incomplete differential service

Installation Notes and Tips

Confirm the axle uses the 10.50″ 1st Design ring gear and rear position before ordering. Match the bearing dimensions and bearing type to the original components during teardown, and inspect the housing, gears, and related sealing surfaces before assembly. Proper setup and preload are important for differential longevity, so follow factory service procedures for the vehicle being repaired.
