Wheel Bearing Service Fresno CA

Worn wheel bearings can often be detected by rocking the vehicle from side to side at low speeds with the steering wheel. This technique tends to increase the load on the bearings, causing the pitted bearing to become noisier than usual. This test works better when the vehicle is warm and in a parking area or roadway with light traffic.

Brake & Wheel Bearing Service

While a wheel bearing must support its share of the vehicle’s weight, it must also maintain a perfect radial alignment with the axle. To illustrate, the instant a brake rotor deviates from a perfect 90-degree alignment with the axle, it pushes the caliper pistons into their bores and allows the brake rotor to drag against the pads.

Even with drum brakes, a wheel bearing must maintain the concentricity of the drum with that of the brake shoes. If the axle bearing allows vertical movement in the axle shaft, the axle shaft is no longer concentric with the brake drum or seal.  The effects are dragging brakes and axle lubricant leaking past the axle seals onto the brake shoes.

WHEEL BEARING NOISES
Because most bearings are case-hardened metal, the bearing race begins to develop pits as the case-hardened metal fatigues and flakes away from the softer base metal. The result is a pitting or pothole effect on the bearing race, which causes a slight knocking or growling noise as the bearing becomes progressively worse. See Photo 1.

One of the difficulties of detecting a worn wheel bearing is that the double ball, sealed bearings used in modern front- and all-wheel-drive axles can develop a pit on the outer race that makes noise only under certain driving conditions. Unfortunately, wheel bearings generally wear only on the load-bearing side. When the vehicle is p...
