Detailed Description

When the pinion seal surface is grooved or worn, a new seal alone often will not correct the leak. The WS99152 repair sleeve provides a new sealing surface over the existing shaft area, helping the seal maintain consistent contact and reducing the need for more extensive driveline repair. This sleeve is sized for shafts with a minimum diameter of 1.52 in and a maximum diameter of 1.526 in, with a 1.859 in flange diameter for the specified applications.

Compatible With 1962-2001 Chevrolet Camaro, rear outer; 1965-1970 Chevrolet Impala, rear outer; 1985-2001 Chevrolet Astro, front outer; and additional listed Chevrolet, GMC, Pontiac, Buick, Oldsmobile, Cadillac, and Isuzu applications. The WS99152 is a fitment-specific driveline hardware solution for vehicles using the noted ring gear and axle configurations.

Common Problems This Part Can Address

• Oil seepage at the differential pinion seal area
• Grooved or worn sealing surfaces on the shaft
• Repeat seal failure after prior repairs
• Reduced sealing consistency caused by shaft wear
• Need for a cost-conscious repair versus shaft replacement

Installation Notes and Tips

Measure the shaft before installation to confirm the 1.52-1.526 in diameter range and verify the flange diameter matches the application. Clean the sealing surface thoroughly before installing the sleeve, and inspect the seal lip for wear or damage before reassembly. The sleeve is designed for straightforward installation without specialized tools in many service situations, but proper measurement and alignment are important for a reliable repair.
