Timken 2008S Differential Pinion Seal - Rear

Timken 2008S Differential Pinion Seal

The Timken 2008S differential pinion seal is built for driveline sealing performance where lubricant retention and contamination control matter. Its S-Nitrile construction, reinforced outer case, and ribbed inner diameter support a secure seal at the pinion area while helping reduce wear from minor shaft imperfections.

Compatible With select axle and driveline applications, this seal is engineered to help maintain proper differential lubrication and keep debris out of the sealing area. Timken 2008S is a practical choice for service work on vehicles such as Chevrolet Silverado and Ford F-150 applications where pinion seal replacement is part of driveline maintenance.

Key Features

• S-Nitrile material for sealing durability and lubricant resistance
• Outside diameter: 2.132 in. / 54.15 mm
• Shaft diameter: 1.260 in. / 32.00 mm
• Housing bore: 2.126 in. / 54.00 mm
• Width: 0.354 in. / 9.00 mm
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter supports sealing on minor spindle imperfections
• Internal contamination exclusion system helps block debris entry
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup

Detailed Description

Timken 2008S is a differential pinion seal designed to retain gear oil at the pinion interface while limiting contamination that can lead to leakage and premature wear. The seal’s precision sealing profile, reinforced case, and vented design work together to support stable operation in demanding driveline environments. This part cross-references Remy 12751 and Standard Ignition 2008 for the same application.

For technicians and DIY repair work, the Timken 2008S offers the dimensional accuracy needed for a proper housing bore fit and shaft contact. It is a strong match for differential service on Chevrolet Silverado and Ford F-150 driveline repairs where the pinion seal is a known wear item. Use the 2008S part number when verifying replacement against existing service information.

What It Helps Fix

• Gear oil leaking from the differential pinion area
• Contamination entering the seal lip and accelerating wear
• Heat-related seal deterioration from poor lubricant circulation
• Leakage caused by minor shaft or spindle surface imperfections
• Noise or driveline service issues tied to low differential lubricant level

Installation Notes and Tips

Confirm shaft diameter, housing bore, and seal width before installation. Clean the bore and sealing surface thoroughly, and inspect the pinion surface for grooves or damage that could affect sealing. Proper seating is important for the Timken 2008S, so install it squarely to avoid distortion and leakage.

When replacing a pinion seal, check the surrounding driveline components for wear, contamination, or lubricant breakdown. Verify the replacement against the 2008S part number and compare dimensions to the original seal before assembly.

Quality Assurance

Timken manufactures oil and grease seals with precision sealing designs intended for dependable lubricant control and contamination exclusion in driveline service.
