SKF 21400 Wheel Seal for Front Axles

SKF 21400 is a front wheel seal built for specific Ford Bronco II and Ford Ranger applications. It uses a nitrile sealing surface and precise dimensions to help maintain proper sealing at the wheel end where lubricant retention and contamination control matter.

Key Features

• Front wheel seal for select Ford Bronco II and Ford Ranger models
• Nitrile sealing surface for dependable contact at the sealing interface
• Outside diameter: 2.910 in.
• Shaft diameter: 2.136 in.
• Width: 0.453 in.

Detailed Description

SKF 21400 is designed for front axle sealing on 1983-1988 Ford Ranger, 1984-1988 Ford Bronco II, and 1989 Ford Bronco II and Ford Ranger models built through 10/89. This wheel seal helps keep lubricant in the hub area and helps block road debris, water, and other contaminants from entering the assembly. The nitrile sealing surface supports consistent sealing performance in the operating environment of these vehicles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Wheel-end grease or lubricant leakage
• Contamination entering the hub or axle area
• Seal wear from age, heat, and road exposure
• Noisy or rough wheel-end operation caused by sealing failure
• Maintenance needs on front axle service for Ford Bronco II and Ford Ranger

Installation Notes and Tips

Verify the seal dimensions before installation and confirm front-position application on the vehicle. Inspect the shaft and sealing surfaces for scoring, corrosion, or debris before pressing in the new seal. Clean the mating area thoroughly and follow the service procedure for the hub or axle assembly to avoid damaging the sealing lip during installation. Confirm fitment for 1983-1988 Ford Ranger, 1984-1988 Ford Bronco II, and 1989 Ford Bronco II / Ford Ranger, front, through 10/89.
