Timken 7457N Differential Pinion Seal - Rear

Timken Differential Pinion Seal 7457N

The Timken 7457N differential pinion seal is built for rear axle applications that need reliable lubricant retention and contamination control. It fits select Pontiac Firebird, Chevrolet Camaro, and Ford E-100 Econoline applications, including 7.75 in. ring gear and 7 in. ring gear configurations listed below.

Key Features

• Precision sealing design helps keep gear oil in the differential and dirt out
• Reinforced outer case resists installation damage and supports seal durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and improve seating
• Internal contamination exclusion system helps block debris that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to reduce heat build-up
• Timken 7457N is a direct-fit differential pinion seal for select rear axle applications

Fitment

• Fits 1985-1991 Pontiac Firebird, rear, fits 7.75 in. ring gear differential bearing.
• Fits 1987-1990 Chevrolet Camaro, rear, fits 7.75 in. ring gear differential bearing.
• Fits 1969 Ford E-100 Econoline, rear, 7 in. ring gear.
• Fits 1969 Ford E-100 Econoline, rear, compatible with manual transmission, 7.25" ring gear, includes differential pinion seal.

What It Helps Address

• Differential oil seepage at the pinion area
• 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 gear oil level

Installation Notes

Confirm axle and ring gear specifications before installation, especially on 1969 Ford E-100 Econoline applications with different rear-end configurations. Inspect the pinion surface for wear, clean the sealing area thoroughly, and install the seal squarely to avoid distortion. Timken 7457N should be matched to the exact rear differential application listed in the fitment data.

Quality Assurance

Timken oil and grease seals use precision sealing designs and reinforced construction to support dependable service in driveline applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
