Detailed Description

InMotion WA512518 is a rear wheel bearing and hub assembly designed as a direct replacement for the original rear hub on select Subaru vehicles. It is built with high-precision manufacturing and strict quality-control standards, using OE data to match the required dimensions and mounting points. This helps support proper wheel mounting, brake alignment, and ABS system function on Subaru Crosstrek, Subaru Impreza, Subaru Forester, and Subaru XV Crosstrek rear applications.

This part number, WA512518, is specified with a 27-spline hub, 5 wheel studs, 4 flange bolt holes, and an integrated ABS sensor. The measured pilot and flange dimensions are important for accurate rear hub fitment, especially when replacing a worn or noisy assembly on a Subaru Crosstrek rear hub, Subaru Impreza rear wheel bearing assembly, or Subaru Forester rear hub assembly.

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