Why This Seal Matters

A worn or leaking seal can lead to fluid loss, contamination, and premature wear in the transmission or axle assembly. SKF 15142 is used to help address fluid seepage at the shaft interface, reduce contamination at the sealing surface, and restore proper sealing in rear inner and rear locations on vehicles such as Ford Bronco, Lincoln Continental, and Jeep Wagoneer.

• Transmission or axle fluid leaking past the seal lip
• Contaminants entering the sealed area
• Wet housing or residue around the shaft opening
• Seal wear from age, heat, or mileage
• Service replacement during drivetrain maintenance

Installation Notes

Verify shaft diameter, housing dimensions, and application notes before installation. Confirm whether the vehicle uses a rear or rear inner position, and check axle or ring gear notes such as Spicer 44, Spicer 60, ball bearing, or axle-load references where listed. Clean the sealing surface thoroughly and inspect the shaft for grooves or damage before fitting the new seal.
