InMotion WS710576 Wheel Seal - Rear

Rear Differential Pinion Seal for Toyota and Lexus

InMotion WS710576 is a rear differential pinion seal built for Toyota Tundra, Toyota Land Cruiser, and Lexus LX570 applications. It uses polyacrylate material and precise dimensions to create a secure barrier at the pinion area, helping keep moisture and road debris out of the differential housing.

Key Features

• Polyacrylate construction for sealing performance and durability
• Inside diameter: 2.441 in; shaft diameter: 2.441 in
• Outside diameter: 3.079 in; housing bore: 3.071 in
• Width: 0.354 in for proper seal profile
• Rear position fitment for select Toyota and Lexus driveline applications
• Part number WS710576 for easy identification

Detailed Description

This differential pinion seal is engineered to maintain a tight seal where the pinion shaft enters the differential, helping preserve internal lubrication and reduce contamination. The measured dimensions support accurate seating in the housing bore and around the shaft, which is important for rear axle service on vehicles such as the Toyota Tundra, Toyota Land Cruiser, and Lexus LX570. If you are replacing a leaking rear pinion seal, WS710576 provides a direct-fit service part for the listed applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Rear differential fluid seepage at the pinion area
• Contamination from water, dirt, and road debris entering the differential
• Seal wear that can lead to lubricant loss
• Noise or driveline concerns associated with low differential fluid
• Service replacement needs on rear axle maintenance for Toyota Tundra, Land Cruiser, and Lexus LX570

Installation Notes and Tips

Confirm the housing bore, shaft diameter, and seal width before installation to match the existing differential housing. Inspect the pinion yoke and sealing surface for wear or scoring, and replace damaged components as needed to help the new seal seat correctly. Clean the bore thoroughly before pressing in the seal, and verify rear-position application before ordering.
