Wheel Bearing Replacement

Sometimes referred to as Wheel Bearing, Wheel Bearing Replace, Replace Wheel Bearing

Wheel bearings allow each wheel to rotate. There are several types of wheel bearings used in automobiles. Some require no maintenance; others can be disassembled, cleaned, and inspected for wear. 

Failing wheel bearings develop excess clearance, or play. One symptom that may develop when the bearing is put "under load" is a distinctive growling noise that can be heard when the wheels are rotating at road speeds.

Wheel bearings are located in the brake drum or brake rotor. Replacing wheel bearings requires the wheel to be removed. Then the brake drum or brake disc is removed, and the wheel bearings are replaced and packed with fresh grease. The wheel bearing may be an integrated part of the vehicle's suspension. If so, the suspension or wheel hub may need to be removed from the vehicle to replace the wheel bearing.
