Timken 223510 Wheel Seal - Left or Rear Inner

Timken Wheel Seal 223510 Overview

Timken 223510 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, a reinforced outer case, and a ribbed rubber inner diameter to help seat against minor spindle imperfections.

Compatible With Audi, Volkswagen, Porsche, and Saab applications including Audi A4, Audi A6, Audi A8, Audi S6, Audi S8, Volkswagen Phaeton, Porsche 911, Saab 900, and Saab 9000. Timken 223510 is also a direct cross-reference to National 223510 for the same application.

Key Features

• S-Nitrile construction for sealing performance in wheel-end service
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter supports sealing on minor spindle imperfections
• Internal contamination exclusion system helps block debris entry
• Vent holes promote lubricant flow around the seal lip to reduce heat build-up
• Precision sealing design helps retain grease and oil at the wheel end

Detailed Description

This Timken wheel seal is engineered around precise dimensions for proper housing and shaft fit: 1.859 in. outside diameter, 1.850 in. housing bore, 1.378 in. shaft diameter, and 0.276 in. width. Those measurements make Timken 223510 a focused replacement for wheel-end sealing service on select Audi, Volkswagen, Porsche, and Saab vehicles. The seal’s internal design helps keep lubricant in place while limiting the entry of dirt and road contamination that can lead to leakage and premature wear.

Use Timken 223510 when servicing wheel-end components on 2006-2008 Audi A4 and A6 left side applications, 2007-2011 Audi S6, 2007-2009 Audi S8, 2004-2006 Volkswagen Phaeton, 1999 Porsche 911 with ZF5HP19HLA notes, 1979-1992 Saab 900, and 1986-1987 Saab 9000.

Search terms such as wheel seal for Audi A4 left, Timken 223510 wheel seal, and Audi A6 wheel seal replacement match this application set.

What It Helps Solve

• Wheel-end grease or oil leakage
• Contamination entering the seal area
• Seal damage during installation
• Poor sealing on slightly worn spindle surfaces
• Heat build-up around the seal lip

Installation Notes and Tips

Confirm housing bore, shaft diameter, and seal width before installation. Clean the spindle and hub sealing surfaces thoroughly, and inspect for scoring, corrosion, or wear that could affect seating. Press the seal in evenly to avoid distorting the reinforced case, and verify that the seal lip is aligned correctly before returning the vehicle to service.
