Detailed Description

Dorman 797-108 is built for rear differential rebuilds where bearing quality and setup accuracy matter. The kit is engineered around 9.25-inch ring gear applications and includes tapered bearings, races, and setup materials that support differential assembly and adjustment. With multiple cone and race dimensions listed for the application, this kit is intended for specific axle configurations rather than universal use.

Compatible With 1994-2000 Dodge Ram 1500, rear; 1994-2000 Dodge Ram 2500, rear; 1994-2000 Dodge Ram 3500, rear; 1998-2000 Dodge Dakota, rear; 1998-2000 Dodge Durango, rear; and additional Chrysler and Dodge rear 9.25-inch ring gear applications. This part cross-references 723A004 for the same application.

What It Helps Repair

• Rear differential bearing noise
• Excessive backlash from worn bearings
• Rough or inconsistent differential operation
• Wear found during ring and pinion service
• Rebuilds on 9.25-inch rear axle assemblies

Installation Notes and Tips

Verify axle identification, ring gear diameter, and fitment details before ordering. Differential setup requires careful measurement of backlash, bearing preload, and gear pattern, so follow factory service procedures during installation. Confirm the correct bearing and race dimensions for the axle being serviced, especially on Dodge Ram, Dakota, and Durango rear differential applications.

Quality Assurance

Dorman positions this kit as a premium service part with high-precision bearings manufactured to tighter tolerances for longer service life than common lower-grade bearings. Use the fitment data and product attributes to confirm application match before installation.
