OE-Style Fit and Dimensions

Beck Arnley 052-3756 is engineered around the critical seal dimensions that matter during service: 61 mm housing bore, 40 mm shaft diameter, and 13 mm overall width with side lip. Those measurements help ensure the seal seats correctly in the transfer case housing and maintains contact at the output shaft, which is essential for controlling fluid at the rear transfer case area. This part is a direct-fit choice for Toyota Tundra, Toyota 4Runner, and Toyota Tacoma rear applications listed below.

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

Installation Notes

Inspect the output shaft surface and housing bore before installation to confirm they are clean and free of damage. Verify the seal orientation matches the transfer case design, and compare the old seal dimensions to the Beck Arnley 052-3756 before pressing it into place. For Toyota 4Runner, Tacoma, and Tundra rear transfer case service, accurate seating is important to maintain a proper seal at the shaft.
