Timken 224270 Wheel Seal - Rear Inner

Timken 224270 Wheel Seal Overview

Timken 224270 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 with a reinforced outer case and a ribbed inner diameter to help seat against minor spindle imperfections.

For wheel seal replacement on axle and hub assemblies, this Timken seal is engineered to keep grease or oil in place while helping block dirt, debris, and moisture from entering the sealing area. It is a direct-fit style service part for applications that call for Timken 224270.

Key Features

• S-Nitrile construction for sealing performance in wheel-end service
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter supports a tighter spindle seal
• Internal contamination exclusion design helps reduce debris intrusion
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup
• Dimensions: 2.845 in. outside diameter, 1.654 in. shaft diameter, 2.835 in. housing bore, 0.394 in. width

Detailed Description

Timken 224270 is a wheel seal designed for axle and hub sealing where consistent lubricant control is critical. The seal’s ribbed inner diameter helps it conform to small spindle irregularities, while the reinforced outer case adds durability during installation and service. Vent holes are included to allow lubricant circulation around the lip, which helps manage heat at the sealing surface. This makes the Timken 224270 a practical choice for wheel-end maintenance on vehicles that require a precise seal profile.

This part cross-references Remy 16555 for the same application.

What This Wheel Seal Helps Address

• Lubricant leakage at the wheel end
• Contamination entering the hub or spindle area
• Seal damage during installation
• Heat buildup at the seal lip
• Poor sealing on minor spindle surface imperfections

Installation Notes and Tips

Verify housing bore, shaft diameter, outside diameter, and width before installation to confirm the seal matches the application. Clean the spindle, hub, and sealing surface thoroughly, and inspect for scoring, corrosion, or wear that could affect sealing performance. Proper seating is important for wheel seal replacement on axle and hub assemblies, including Timken 224270 applications on Ford F-150 and Chevrolet Silverado 1500 service jobs.
