Detailed Description

WB513106 is engineered as a universal-style wheel bearing for automotive and industrial use, with the dimensional profile needed for accurate fitment in supported vehicles. The bearing’s ball design helps maintain smooth wheel rotation while minimizing friction, and the two-row layout supports consistent operation under everyday road loads. InMotion WB513106 is a practical service part for BMW 325i, BMW 328i, Porsche 911, and Porsche Boxster wheel-end repairs where the specified dimensions and position match the original application.

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

What It Helps Fix

• Wheel-end noise such as humming or growling
• Excessive wheel play or looseness
• Rough rotation caused by worn bearing surfaces
• Vibration related to bearing wear
• Reduced wheel stability from deteriorated support components

Installation Notes and Tips
