Timken 7216 Differential Pinion Seal - Rear

Timken 7216 Differential Pinion Seal

Timken 7216 is a rear differential pinion seal built for Chrysler and Dodge applications that need reliable lubricant retention at the pinion shaft. It is a direct-fit sealing component for classic Mopar rear ends, including Dodge Challenger, Charger, Dart, and Chrysler Imperial, Newport, and New Yorker applications.

Key Features

• Precision sealing design helps keep gear oil inside the differential and contaminants out
• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and supports a secure seat
• 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 fits applications with an 8.75 in. ring gear and 1.75 in. pinion shaft O.D. on select Dodge Challenger, Charger, and Dart models, along with Chrysler Imperial, Newport, and New Yorker vehicles. Timken 7216 is a practical replacement when servicing a leaking rear pinion area on classic Mopar driveline assemblies.

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

What It Helps Fix

• Rear differential gear oil seepage at the pinion shaft
• Contamination entering the pinion seal area
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor shaft surface imperfections
• Seal damage from prior installation or removal

Installation Notes and Tips

Verify rear axle configuration before ordering, including the 8.75 in. ring gear and 1.75 in. pinion shaft O.D. noted in the fitment data. Clean the seal bore and pinion surface thoroughly before installation, and inspect the shaft for wear, grooves, or corrosion that could affect sealing performance. Timken 7216 fits rear applications only.

Quality Assurance

Timken oil and grease seals use precision sealing designs, a reinforced outer case, and contamination-exclusion features to support dependable service in driveline applications.
