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 become loose and 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.
To service vehicles with serviceable wheel bearings, the wheel must be removed. Then the bearings, brake drum, brake rotor, or wheel hub assembly is removed. The wheel bearings are removed, cleaned, and inspected. If they are OK, they are packed with fresh grease and re-installed. If they show signs of wear, they need to be replaced.
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 to replace the wheel bearing.
