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

What It Helps Address

• Transmission or drivetrain fluid seepage at the seal surface
• Contamination from dirt, dust, and moisture entering the assembly
• Wear-related sealing loss at the output shaft area
• Service issues on Toyota and Lexus axle or ring gear applications
• Noise or drivability concerns caused by low fluid levels from leaks

Installation Notes and Tips

Confirm the seal dimensions against the housing bore and shaft diameter before installation. Inspect the shaft surface for grooves, corrosion, or scoring, since surface damage can shorten seal life. Clean the bore thoroughly, seat the seal evenly, and verify the application notes for the exact position, including front, rear, front outer, or rear outer where listed. For fitment-specific service, use the vehicle notes such as Toyota axle, 7.8in ring gear, or Aisin N40 transmission to match the correct application.
