Installation Notes

Verify rear fitment by year, make, and model before ordering. MB50328 is a rear hub assembly with pre-greased construction and included hardware, which can reduce prep time during installation. Confirm that your vehicle does not require an integrated ABS sensor in the hub, since this assembly does not include one. Use proper torque procedures and inspect the mating surfaces, axle area, and surrounding brake components during service.
