Timken 710481 Differential Pinion Seal - Rear

Timken 710481 Differential Pinion Seal

Timken 710481 is a rear differential pinion seal built to retain gear oil and keep contaminants out of the axle assembly. It is a direct-fit service part for a wide range of Ram, Dodge, Chrysler, and Mitsubishi rear axle applications, including Ram 1500 and Dodge Dakota models.

Key Features

• Precision sealing design helps control lubricant loss at the pinion area
• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and seat securely
• Internal contamination exclusion system helps block debris that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup

Detailed Description

This Timken differential pinion seal is engineered for rear axle service where the pinion shaft passes through the differential housing. It is used on applications such as 2011-2018 Ram 1500 rear, 2000-2010 Dodge Dakota rear, and 2007-2010 Dodge Nitro rear, along with other listed Ram, Dodge, Chrysler Aspen, and Mitsubishi Raider rear axle fitments. The part number 710481 is a practical choice when replacing a leaking pinion seal during differential maintenance.

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

What It Helps Address

• Rear differential gear oil seepage at the pinion seal
• Contamination entering the axle housing through a worn seal
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor surface imperfections at the sealing area
• Noise or driveline concerns associated with low differential lubricant level

Installation Notes and Tips

For several listed applications, the Differential Pinion Race must be used with the Differential Pinion Seal for proper installation. Confirm rear axle configuration before ordering, and inspect the pinion yoke, sealing surface, and surrounding components for wear before assembly. Timken 710481 is listed for rear position use only.
