Detailed Description

The Dorman 797-120 differential bearing kit is engineered for differential rebuilds where bearing precision matters. The kit uses tapered steel bearings with tighter tolerances than common lower-grade replacements, helping reduce backlash-related issues inside the differential and supporting long-term service life. It is a practical choice for rear axle work on 2001-2010 Dodge Dakota, 2001-2010 Dodge Ram 1500, 2001-2010 Dodge Ram 2500, 2001-2010 Dodge Ram 3500, and 2001-2009 Dodge Durango applications with a 9.25-inch ring gear.

This part cross-references Monroe Shocks & Struts (e.g., 723A004B) for the same application. Use Dorman 797-120 when rebuilding a rear differential and you need a bearing kit that matches the axle setup and simplifies the repair process.

What It Helps Fix

• Excess differential bearing wear or rough bearing operation
• Noise from worn pinion or carrier bearings
• Backlash concerns during differential rebuilds
• Loss of smooth gear engagement after bearing failure
• Time lost sourcing individual differential service components

Installation Notes and Tips

Confirm axle configuration, ring gear diameter, pinion spline count, and bearing dimensions before installation. Differential setup requires careful measurement of preload, backlash, and gear pattern, so follow factory service procedures during assembly. Verify fitment against the vehicle application and rear axle notes before ordering.
