Detailed Description

This Dorman differential ring and pinion, part number 697-353, is built for vehicles that use a 4.10 axle ratio and the specified rear differential configuration. It is a direct OE replacement for select applications across Ford F-150, Ford Explorer, Ford Expedition, Lincoln Navigator, Mercury Mountaineer, and related platforms, making it a practical choice when restoring driveline gearing after wear or damage. The ring gear and pinion dimensions, including the 10.25-inch ring gear outside diameter and 2-inch pinion shaft diameter, align with the listed applications for proper differential service.

This part cross-references Monroe Shocks & Struts (e.g., 764A730G) for the same application.

Common Issues This Part Can Address

• Worn or damaged ring and pinion gear teeth
• Noise from the rear differential under load or deceleration
• Incorrect axle ratio after differential service
• Loss of driveline performance caused by gear wear
• Need for OE-style replacement gearing in rear axle repairs

Installation Notes and Tips

Installation requires differential setup procedures, including gear pattern verification, backlash adjustment, and bearing preload checks. Shims are not included, and installation hardware is not included. Confirm the axle configuration and rear application before ordering, especially on Ford F-150, Ford Explorer, and Lincoln Navigator models listed with 4.10 or 4.88 axle ratio notes in the fitment data. Proper setup is critical for quiet operation and long gear life.

Quality Assurance

Dorman supplies this as a standard replacement part engineered to directly replace the original equipment on the listed vehicles. Part number 697-353 is intended for specific rear differential applications and should be matched to the vehicle’s axle ratio and differential specifications before installation.
