Dorman 797-100 Differential Bearing Kit - Front or Rear
Dorman 797-100 Differential Bearing Kit
Restore differential performance with a premium bearing kit built for front and rear axle service. Dorman 797-100 uses high-precision, tapered steel bearings with tighter tolerances to reduce backlash and support longer service life in demanding driveline applications.
Key Features
- Premium differential bearing kit for front or rear differential rebuilds
- High-precision tapered bearings engineered to tighter tolerances
- Steel bearing construction for durability in torque-heavy driveline use
- Bearing races included for a complete service setup
- Includes setup components such as shims, crush collar, gasket material, thread lock compound, gear marking compound, hardware, and application brush
- Sealed bearing design
- Fits applications with an 8.5 in. ring gear and 10 ring gear bolts
- Designed for 30-spline pinion applications
Detailed Description
Dorman 797-100 is a differential bearing kit for servicing rear and select front differentials in GM trucks, SUVs, and passenger cars. It is built around tapered steel bearings with multiple cone and race dimensions listed for proper differential setup, including 33.34 mm and 41.28 mm cone inside diameters, 68.26 mm, 73.43 mm, and 82.55 mm cone outside diameters, and 38 mm and 46 mm race inside diameters. This kit is intended for 8.5-inch ring gear differentials and is a direct fit for many Chevrolet, GMC, Cadillac, Buick, Oldsmobile, and Pontiac applications. This part cross-references 741A004 for the same application.
Compatible vehicle coverage includes rear differential service on the Chevrolet C1500, K1500, Tahoe, Blazer, S10, and GMC Yukon, Jimmy, Sonoma, and C1500/K1500 platforms, plus front differential applications on select Chevrolet and GMC 4x4 models. Dorman 797-100 is a practical choice when rebuilding a differential on a Chevrolet C1500 rear axle, GMC Yukon rear axle, or Chevrolet K1500 front axle and you need the bearing components and setup materials in one kit.
What It Helps Fix
- Excessive differential bearing wear or rough bearing operation
- Noise from worn pinion or carrier bearings
- Backlash issues caused by lower-grade bearing components
- Time lost sourcing individual differential service parts
- Incomplete differential rebuilds when races and setup materials are needed
Installation Notes and Tips
Verify the axle configuration, ring gear diameter, and fitment details before ordering. This kit is listed for both rear and select front positions, so confirm the exact application on your Chevrolet, GMC, Cadillac, Buick, Oldsmobile, or Pontiac vehicle. Differential setup requires careful measurement of bearing preload, backlash, and gear pattern, so follow factory service procedures during installation.
Quality Assurance
Dorman positions this kit as a premium differential service solution with precision bearings manufactured to tighter tolerances for improved durability in differential use. The included races and setup materials support a more complete rebuild process for compatible GM driveline applications.
