Detailed Description

SKF 16545 is a differential pinion seal engineered for rear driveline service where the pinion shaft passes through the axle housing. SKF has a long history in seal design and uses premium materials and application-specific construction to help maintain proper sealing performance in the operating environment. This seal is specified with a 2.627-inch outside diameter, 1.656-inch shaft diameter, and 0.375-inch width, with a polyacrylate sealing surface type.

Compatible With rear axle service on 1985-1991 Pontiac Firebird, 1987-1990 Chevrolet Camaro, 1987-1988 Chevrolet Monte Carlo, 1987 Chevrolet El Camino, 1969 Ford E-100 Econoline, and 1961-1967 Ford Econoline in the listed rear differential configurations. The SKF 16545 is a practical choice when replacing a worn pinion seal on vehicles that need reliable lubricant retention and contamination control.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination entering the rear axle housing
• Seal wear from age, heat, and driveline use
• Noise or driveline issues caused by low lubricant level
• Service replacement for rear differential maintenance

Installation Notes and Tips

Verify axle and ring gear configuration before ordering, especially on Ford Econoline applications with WCC axle and 7.00-inch or 7.25-inch ring gear notes. Inspect the pinion yoke and sealing surface for wear or grooves before installation, and confirm the seal dimensions match the housing and shaft requirements. Clean the sealing area thoroughly so the new seal seats evenly and maintains proper contact.

Quality Assurance

SKF manufactures seals to defined specifications using materials selected for the application and operating environment. The brand’s seal engineering focus supports consistent fit and long service life in driveline sealing applications.
