What Is Behind Wheel Bearing Noise?
A caliper that’s sticking or a brake pad that’s loose and dragging may make a metallic scraping noise.
VIDEO: Finding The Right Hub Unit Using The VIN
Andrew Markel shows how using vehicle information such as the VIN and trim level can help you zero in on the right hub unit. Sponsored by BCA Bearings.
VIDEO: Clicking Noise After Wheel Hub Replacement
If a customer complains of a clicking noise after a hub unit has been replaced, two OEMs have each prepared their own solution to the problem, and they happen to be nearly identical. Sponsored by BCA Bearings.
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.
Subaru Tech Tip: Error Codes Following Wheel Bearing Hub Replacement
On the hubs for 2005-2014 Subaru Legacy and Outback applications, a speed sensor mounts into the knuckle. It’s exposed end extends out behind the bearing to capture pulses from an encoder ring on the back of the bearing.
Preventing ABS Sensor Failure In Pigtail-Style Hub Assemblies
ABS system failures that happen shortly after hub unit installation can cause concern for technicians and dissatisfaction for customers. Several items should be checked during replacement to prevent comebacks.
The Case for On-Car Wheel Balancing and Wheel-to-Hub Indexing
Off-car wheel balancers do an excellent job of measuring dynamic unbalance — static and couple — and many also measure tire/wheel uniformity, radial runout or calculate radial force variation (RFV) to help eliminate vibration and verify the assembly is balanced and round when rolling. However, two problematic assumptions are made with off-car balancers: 1. That
Wheel Bearings: Measurement and Torque
Wheel bearings are either of the ball or tapered roller variety. Front wheel bearing applications are an angular-type ball bearing, which will accept greater thrust loads than a Conrad-type bearing, and will accept a 100 percent load in the radial or thrust position and any combination of a 100 percent load. A tapered roller bearing
