• High-precision tapered bearing design for differential service
• Engineered with tighter tolerances than common lower-grade bearings
• Includes bearing races for a complete bearing replacement
• Steel bearing construction for drivetrain durability
• Supports front or rear differential repair and rebuild work
• Package contents include bearings, races, shims, crush collar, gasket material, gear marking compound, thread lock compound, application brush, and hardware

Detailed Product Overview

The Dorman 797-113 is a differential bearing kit for rebuilding or repairing a differential where bearing wear, noise, or gear setup issues are present. It includes tapered bearings with multiple measured dimensions, including 64.29 mm, 73.43 mm, and 76.20 mm outside diameters, along with matching race sizes and steel construction for service in torque-loaded differential assemblies. The kit is intended to save time during differential work by reducing the need to source individual components separately.

This part number is a practical choice for rear differential service on Chevrolet Impala, Camaro, Nova, Caprice, Monte Carlo, and El Camino models, as well as Pontiac Catalina applications listed for the 8.2 in. axle. Dorman 797-113 is also a useful reference when searching for a differential bearing kit for classic GM rear axle rebuilds.

What It Helps Fix

• Differential bearing noise from worn or rough bearings
• Excessive backlash caused by bearing wear
• Gear setup problems during differential rebuilds
• Loss of bearing support in high-torque axle service
• Time spent sourcing separate differential service components

Installation Notes and Tips

Verify axle type, ring gear diameter, pinion spline count, and bearing dimensions before ordering. This kit is listed for 8.2 in. axle applications and rear position use on the vehicles shown in the fitment data. Differential setup requires careful measurement of bearing preload, backlash, and gear contact pattern; follow service manual procedures during installation.
