Detailed Description

Dorman 797-105 is a differential bearing kit intended for rear axle service on a wide range of classic Chevrolet and GMC trucks, vans, and SUVs. Fitment includes 1975-1982 Chevrolet C10 and K10, 1975-1981 Chevrolet C20, 1975-1981 Chevrolet G10 and G20, 1975-1981 Chevrolet K5 Blazer, 1970-1981 GMC Jimmy, and related C1500, K1500, C2500, and G-series applications with an 8.875-inch ring gear. The kit is also listed for select 1964-1966 GMC G1500 and G1000 Series models.

Built around tapered steel bearings, this kit is aimed at differential rebuilds where bearing precision, race fit, and setup accuracy matter. The included races, shims, pinion nut, seals, and marking compound support differential assembly and gear pattern verification. If you are servicing a rear differential on a Chevrolet C10, GMC K1500, or GMC Jimmy, this kit provides the core components needed for bearing replacement and setup.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Excess differential bearing noise
• Rough or worn bearing surfaces during rebuild
• Improper gear mesh caused by worn bearings or races
• Backlash issues related to bearing wear
• Time lost sourcing separate differential service components

Installation Notes and Tips

Verify ring gear diameter, pinion spline count, and bearing dimensions before ordering. This kit lists multiple cone and race dimensions, so confirm the application against your differential specifications and fitment details. During installation, inspect the housing, gears, and carrier for wear, and use the included marking compound to check gear contact pattern after setup.

Quality Assurance

Dorman designs this premium differential kit with tighter manufacturing tolerances than common lower-grade bearings to support long-term service in differential rebuilds. Review the product attributes and vehicle fitment carefully to confirm the correct application before installation.
