Common Repair Uses

• Rear differential bearing noise during acceleration or deceleration
• Gear oil seepage at the differential seals

• Service work on a 7.5 in. or 7.63 in. ring gear rear axle
• Restoration or maintenance on Chevrolet Camaro, Pontiac Firebird, and Isuzu Rodeo rear differentials

Installation Notes

Confirm the ring gear size, pinion bearing dimensions, seal I.D., and axle design before ordering. This kit is listed for rear applications only, and several vehicles require matching the exact differential configuration noted in the fitment data. Professional differential setup procedures are recommended after bearing and seal replacement.
