Detailed Description

InMotion WS711181 is a precision-engineered seal made to maintain a reliable barrier where the shaft passes through the housing. The fluoro-elastomer sealing material is selected for demanding drivetrain environments, helping resist contamination from debris and moisture while supporting consistent sealing at the differential pinion area. With matched dimensions for the inside diameter, outside diameter, and housing bore, this seal is specified for direct-fit service across many Honda and Acura platforms. It is a practical replacement choice for vehicles such as the Honda Odyssey, Honda Pilot, Acura MDX, and Acura TLX when a dependable seal is needed to control leakage and protect internal components. This part number WS711181 is also a useful reference when sourcing the correct seal for Honda and Acura differential service.

What This Seal Helps Address

• Fluid seepage at the differential pinion seal area
• Contamination from road debris and moisture entering the seal interface
• Wear-related sealing loss at the shaft and housing bore
• Service issues tied to aging or hardened seal material
• Protection of sensitive internal differential components

Installation Notes and Tips

Verify shaft diameter and housing bore dimensions before installation to confirm proper seating. Clean the sealing surface thoroughly and inspect the mating area for scoring, corrosion, or debris that could affect the seal. Use standard drivetrain service procedures and follow the vehicle manufacturer’s specifications for the application. Confirm the vehicle’s year, make, and model against the fitment list before ordering.
