Dorman 797-102 Differential Bearing Kit - Rear

Dorman 797-102 Differential Bearing Kit

Restore differential performance with the Dorman 797-102 differential bearing kit. Built for rear axle service on a wide range of Chevrolet, GMC, Buick, Pontiac, Oldsmobile, and Isuzu applications, it provides high-precision tapered bearings selected for tighter tolerances and longer service life than common lower-grade replacements.

This kit is a practical choice for rear differential rebuilds on vehicles such as the Chevrolet Camaro, Chevrolet S10, and Pontiac Firebird with a 7.5 in. ring gear. It also helps reduce the time spent sourcing individual differential service components.

Detailed Description

Dorman 797-102 is a differential bearing kit for front or rear differential rebuild work, with fitment listed here for rear applications using a 7.5 in. ring gear. The kit uses tapered bearings and includes bearing races to support accurate setup during differential service. With multiple cone and race dimensions listed in the product data, this kit is intended for specific axle configurations rather than universal use. For buyers searching for a rear differential bearing kit for Chevrolet Camaro, Chevrolet S10, or Pontiac Firebird, 797-102 provides a consolidated service solution for the bearing replacement portion of the job.

This part cross-references Monroe Shocks & Struts (e.g., 742G004) for the same application.

What It Helps Fix

• Excessive differential bearing wear
• Noise from worn rear axle bearings
• Backlash issues caused by degraded bearing surfaces
• Rough or inconsistent differential operation during rebuilds
• Time lost sourcing individual differential service parts

Installation Notes and Tips

Verify ring gear diameter, bearing dimensions, and axle configuration before ordering. This kit is listed for rear 7.5 in. ring gear applications, so confirm the vehicle’s differential setup against the fitment data before disassembly. During installation, follow standard differential setup procedures for bearing preload, shim selection, and gear marking checks to confirm proper contact pattern.

Quality Assurance

Dorman positions this kit as a premium differential service component with bearings manufactured to tighter tolerances for durability and consistent operation. The included races support a complete bearing replacement during differential rebuild service.
