What Is Behind Wheel Bearing Noise?
The classic symptom of a bad wheel bearing is typically a cyclic chirping, squealing or growling noise.
Wheel Bearing Service – The Complete Guide
Wheel bearing service information is vital for writing accurate estimates. But, experience is key.
Wheel Bearing Technology: Don’t Become Complacent
Wheel bearings are changing because the vehicles they are attached to and the brake rotors located on the other side are evolving. This has changed the designs and specifications for most bearings.
Steering and Suspension Inspection: Keeping The Angles In Line With Ackermann
When you consider how front suspensions have evolved from straight axles to independent designs, the tie rod has had to adapt to new angles and geometry.
Ex’Splining’ New Wheel Bearing Designs
From an engineer’s perspective, wheel bearing design and selection can be a balancing act between durability, cost and fuel economy.
How Noise, Vibration & Harshness Diagnostics Is Changing
The topic of noise, vibration and harshness (NVH) diagnostics came home to me 20 years ago when I began dabbling in collector car repairs. Customers soon began complaining about wind noise and chassis vibrations in ’60s-era cars. Back then, these complaints weren’t repairable because good NVH abatement technology had yet to be developed. Today, that is not the case.
New Wheel Bearing Technology Will Change Your Replacement & Diagnostic Approach
Two technologies are now being used on new vehicles and in aftermarket replacement hub units that allow engineers to put better bearings in smaller packages. These technologies will change the way you replace and diagnose wheel bearings.
Common Reasons For Wheel Bearing Failure
When a bearing wears out, it is usually a case of inadequate lubrication, faulty installation or improper adjustment. For the repair to be successful, you must first determine why the previous bearing failed. For sealed hub units, examining the internal bearings and races is impossible.
Impact Damage On Wheel Hubs
When a driver hits a pothole or curb hard enough, extreme forces are put onto the balls or rollers and races of the bearing. This can result in the formation of a very small mark on the surfaces. The driver might go 1,000 miles or more before these components start making noise.
Wheel Bearings: Diagnostics, Removal And Installation
The classic symptom of a bad wheel bearing is typically a cyclic chirping, squealing or growling noise that changes in proportion to vehicle speed.
