Dorman 797-119 Differential Bearing Kit - Rear

Differential Bearing Kit for Rear Axle Service

Dorman 797-119 is a premium differential bearing kit for rear differential rebuilds and bearing replacement service. It is built with high-precision steel bearings made to tighter tolerances for smoother operation and reduced backlash under differential torque.

Compatible With rear 8.5-inch ring gear applications on Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and other listed GM-platform vehicles.

Key Features

• High-precision tapered differential bearings for front or rear differential service
• Steel bearing construction for durability in drivetrain applications
• Includes bearing races for a complete bearing replacement service
• Package contents include bearings, races, shims, crush collar, gasket material, gear marking compound, thread lock compound, application brush, and hardware
• Designed for 8.5-inch ring gear applications with a 30-spline pinion count
• Dorman part number 797-119 for differential rebuild and service identification

Detailed Description

This Dorman differential bearing kit is intended for rear axle service where precision and bearing longevity matter. The kit uses tapered steel bearings with multiple cone and race dimensions to match the differential setup, helping restore proper bearing support during rebuild work. It is a practical choice for technicians servicing GM trucks and SUVs with an 8.5-inch ring gear, including Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade applications. Dorman 797-119 also cross-references 742G004A for the same application.

What It Helps Solve

• Excess differential bearing play or backlash
• Noise from worn pinion or carrier bearings
• Rough operation during rear differential rebuilds
• Loss of bearing preload after wear or teardown
• Need to source individual differential service components separately

Installation Notes and Tips

Verify axle configuration, ring gear diameter, pinion spline count, and bearing dimensions before installation. Use the included gear marking compound to confirm gear contact pattern during setup, and follow differential preload and shim specifications for the vehicle. This kit is listed for rear position applications only, so confirm rear axle fitment before ordering.

Quality Assurance

Dorman engineers this kit with tighter manufacturing tolerances than common lower-grade bearings to support longer service life in differential rebuild applications. Check the fitment details and product attributes to confirm the correct application for your vehicle.
