MPA Electrical WH512536 Wheel Bearing and Hub Assembly - Rear
Rear Wheel Hub Assembly for Subaru Applications
MPA Electrical WH512536 is a rear wheel bearing and hub assembly built for select Subaru models with ABS encoder integration. It is a new steel hub assembly with a 5-lug, M12 x 1.25 stud pattern, 27 splines, and an included flange, gasket, and seal for a direct-fit replacement in the rear suspension.
Compatible with 2015-2018 Subaru Outback rear, 2015-2016 Subaru Legacy rear, 2015-2016 Subaru WRX rear, and 2015-2016 Subaru WRX STI rear. The WH512536 is a practical choice when replacing a worn rear hub on Subaru Outback, Legacy, WRX, or WRX STI models that use an encoder-style ABS system.

Fitment and Application Details
This hub assembly is engineered for rear position service on Subaru Outback, Legacy, WRX, and WRX STI applications listed above. It cross-references OE part number 28473-VA000 for the same application. Use the WH512536 when the original rear hub shows bearing wear, ABS signal issues, or mounting damage.
Common Problems This Part Can Address
- Rear wheel bearing noise or rough rotation
- ABS warning light caused by encoder-related hub wear
- Excessive wheel play from a worn hub assembly
- Damaged or corroded hub mounting surfaces
- Uneven rear wheel stability from hub deterioration
Installation Notes and Tips
Rear axle nut torque specification should be verified in the OE service manual for the vehicle being serviced. Confirm spline count, flange dimensions, stud pattern, and ABS encoder style before installation. Because the anti-lock brake sensor is not included, reuse or replace the sensor as needed based on the vehicle condition.
