Timken 224255 Wheel Seal - Front, Rear, Rear Left or Rear Outer

Timken Wheel Seal for Driveline Service

Timken 224255 is a wheel seal built for driveline and axle sealing applications where lubricant retention and contamination control matter. It is a direct-fit style seal for select Mitsubishi, Dodge, Chrysler, Pontiac, and Chevrolet applications, including Mitsubishi Mighty Max, Montero, and Starion service needs.

Key Features

• N-Polyacrylate sealing material for durable performance in grease and oil sealing applications
• Reinforced outer case helps resist installation damage and supports long-term seal integrity
• Ribbed rubber inner diameter helps seal minor spindle imperfections and promotes positive spindle seating
• Internal contamination exclusion system helps block debris that can lead to leakage
• Vent holes allow lubricant flow around the seal lip to reduce heat build-up
• Outside diameter: 2.565 in. (65.15 mm); housing bore: 2.559 in. (65.00 mm); shaft diameter: 1.654 in. (42.00 mm); width: 0.394 in. (10.00 mm)

Detailed Description

This Timken wheel seal is engineered to help maintain proper lubrication at the wheel end or axle assembly while keeping contaminants out of the sealing area. The precision sealing design, reinforced outer case, and ribbed inner diameter work together to support a secure fit on the spindle or shaft surface. Timken 224255 is a practical replacement choice for vehicles such as the Mitsubishi Mighty Max, Mitsubishi Montero, Mitsubishi Starion, Dodge Challenger, and Dodge Colt when the application calls for this seal size and configuration. This part cross-references National 224255 for the same application.

What This Part Helps Address

• Gear oil or grease leakage at the wheel seal area
• Contamination entering the hub or axle sealing surface
• Seal seating issues caused by minor spindle imperfections
• Heat-related seal wear from poor lubricant circulation
• Noise or service concerns tied to degraded axle or wheel-end sealing

Installation Notes and Tips

Verify shaft diameter, housing bore, outside diameter, and width before installation to confirm proper fit. Inspect the spindle or sealing surface for scoring, corrosion, or burrs, and clean the bore thoroughly before pressing the seal into place. Use care during installation to avoid distorting the reinforced outer case or damaging the sealing lip. For fitment-specific service, this seal fits 1983-1993 Mitsubishi Mighty Max, front; 1983-1988 Mitsubishi Mighty Max, rear; 1983-1989 Mitsubishi Montero, front; 1983-1988 Mitsubishi Montero, rear; 1987-1988 Mitsubishi Van, rear; 1984-1987 Mitsubishi Starion, rear, non limited slip differential; 1985-1986 Dodge Conquest, rear, non limited slip differential; 1987 Chrysler Conquest, rear outer, non limited slip differential; 1980-1983 Dodge Challenger, rear; 1978-1980 Dodge Colt, rear outer; 1985-1991 Pontiac Firebird, rear left, fits 7.75 in. ring gear differential bearing; and 1987-1990 Chevrolet Camaro, rear left, fits 7.75 in. ring gear differential bearing.
