SKF 22610 Differential Pinion Seal - Rear

SKF 22610 Differential Pinion Seal

The SKF 22610 differential pinion seal is built for rear axle sealing performance on select Chrysler applications. It uses a nitrile sealing surface and precise dimensions to help maintain lubricant control at the pinion shaft area.

Key Features

• Part number: 22610
• Outside diameter: 3.570 in.
• Width: 0.438 in.
• Shaft diameter: 2.250 in.
• Nitrile sealing surface for axle and driveline sealing applications
• Engineered for rear differential pinion use

Detailed Description

SKF has a long history in seal design, including early integrated shaft seal development and continued refinement of bonding and material selection. The SKF 22610 differential pinion seal is manufactured to specific design requirements using premium sealing materials to help keep gear lubricant contained at the pinion and reduce contamination at the axle end. This part number 22610 is a direct-fit sealing component for rear differential service on 1951-1954 Chrysler Imperial, Chrysler New Yorker, and Chrysler Town & Country models.

This part cross-references Chrysler OE-style applications such as 1327893 and 145822610 for the same rear differential pinion seal use. For restorations and driveline repairs on Chrysler Imperial, New Yorker, and Town & Country vehicles, SKF 22610 provides the dimensional accuracy needed for proper sealing at the pinion shaft.

What It Is Used For

• Stopping gear oil seepage at the rear differential pinion
• Reducing contamination entry into the axle housing
• Replacing a worn or hardened pinion seal during differential service
• Addressing leaks that can leave lubricant residue around the pinion area
• Supporting proper rear axle lubrication retention on Chrysler Imperial, New Yorker, and Town & Country models

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the SKF 22610 matches the axle housing and pinion dimensions. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion before fitting the new seal. Clean the sealing area thoroughly and install the seal squarely to avoid distortion or premature leakage. Confirm rear-position application before ordering.

Quality Assurance

SKF seals are produced to high manufacturing standards with application-specific materials selected for the operating environment. The brand’s seal engineering focus and long-running OE and aftermarket experience support consistent fit and sealing performance for driveline service.
