Rear Wheel Bearing: The Ultimate Guide to Maintenance and Replacement

Rear wheel bearings are crucial components that play a vital role in ensuring the smooth and safe operation of your vehicle. They allow the wheels to rotate freely while supporting the weight of the vehicle and its occupants. Regular maintenance and proper replacement of rear wheel bearings are essential to prevent costly repairs and potential accidents.

Types of Rear Wheel Bearings

Type	Description
Single-row ball bearing	Most common type; provides axial and radial support
Double-row ball bearing	Similar to single-row but with two rows of balls for increased load capacity
Tapered roller bearing	Designed for heavy-duty applications; can withstand high axial and radial forces

Signs and Symptoms of Rear Wheel Bearing Failure

Symptoms	Causes
Grinding or humming noise while driving	Worn or damaged bearings
Vibration in the steering wheel or seat	Loose or defective bearings
