Timken 2146 Wheel Seal for Driveline Service

Timken 2146 is a wheel seal built for driveline and axle sealing applications where lubricant retention and contamination control matter. It uses an S-Nitrile sealing material, a reinforced outer case, and a ribbed inner diameter to help seat against minor spindle imperfections.

Fits 1998-2004 Jeep Grand Cherokee, rear; fits 2002 Jeep Liberty, rear; fits 2001 Jeep Cherokee, rear; and other listed Jeep, Ford, and Hyundai applications with Dana/Spicer and KSC axle configurations.

• S-Nitrile construction for sealing performance in axle and wheel-end service
• Reinforced outer case helps reduce installation damage and improve durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections
• 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
• Bi-directional helix type for use in the specified applications

This Timken wheel seal is engineered to retain oil and grease while keeping contaminants out of the sealing area. It is a direct-fit service part for a range of rear axle and wheel-end applications, including Jeep Grand Cherokee, Jeep Liberty, and Jeep Cherokee models listed in the fitment data. The Timken 2146 is also cross-referenced to National 2146 for the same application.

Common Problems This Seal Helps Address

• Axle lubricant leakage at the wheel end
