Installation Notes and Tips

Confirm the vehicle position before installation, since WB510081 is used in both front and rear applications depending on model. Verify the 49 mm inside diameter, 90 mm outside diameter, and 45 mm width against the removed part before assembly. Because this bearing includes ABS encoder functionality, inspect the tone/encoder side and sensor condition during service. Professional installation is recommended for proper hub alignment and bearing seating.
