Key Features

• Precision sealing design for transfer case output shaft service
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter seals minor spindle imperfections and supports positive seating
• Internal contamination exclusion system helps reduce debris intrusion
• Vent holes promote lubricant flow around the seal lip to help manage heat

What This Seal Helps Address

• Transfer case fluid seepage at the output shaft
• Contamination entering the sealing area
• Seal wear from heat buildup around the lip
• Leak issues caused by minor shaft surface imperfections
• Damage during seal installation

Installation Notes

Inspect the shaft surface, housing bore, and sealing area before installation. Clean all mating surfaces thoroughly and verify correct orientation of the seal lip. Some listed Chevrolet and GMC rear applications note that a differential pinion race must be used with the differential pinion seal for proper installation. Confirm vehicle position and transfer case or axle configuration before ordering.

Quality Assurance

Timken oil and grease seals use reinforced construction and contamination-control features to support reliable sealing performance in drivetrain service.
