Detailed Description

This Timken wheel seal is engineered for rear driveline sealing service on a wide range of classic applications, including Jeep Comanche, Jeep J10, Jeep J20, Buick Skylark, Chevrolet Monte Carlo, Oldsmobile Cutlass, Pontiac GTO, and related rear axle platforms.

Installation Notes and Tips

Verify axle type, ring gear size, and rear position before installation. Confirm the vehicle-specific notes for Dana/Spicer 35, Buick B, Oldsmobile O, or 10-bolt housing applications, since fitment varies by model and drivetrain configuration. Clean the sealing surface thoroughly and inspect the spindle or shaft for wear, scoring, or corrosion before installing Timken 712146.
