What This Bearing Helps Address

• Excessive friction in differential pinion or axle support points
• Noise or roughness from worn taper bearing surfaces
• Loss of rotational stability in driveline assemblies
• Service needs on front outer, rear outer, front inner, and rear inner bearing locations
• Replacement requirements for vehicles using specific axle or transmission codes

Installation Notes and Quality Assurance

Verify inside diameter, width, cone radius, axle type, ring gear size, and transmission code before installation. Because fitment varies by axle and drivetrain configuration, match the vehicle application exactly to the listed notes for the correct service position. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

InMotion manufactures this bearing from high-quality materials for consistent operation and durability across automotive and industrial environments. The WTM88048 is intended for applications where dependable bearing support and long service life are required.
