Wheel Bearing Warning Signs Symptoms Auto Repair Blog

14/5/2019 The wheel bearings fit tightly inside this hub, and ride on a metal axle shaft, helping reduce friction when the wheel spins These are different from the engine bearings, as there is no constant source of lubrication for the wheel bearings, which means they need to be tight enough to keep away water and road dust

Journal Bearings

The purpose of a bearing is to support a load, typically applied to a shaft, whilst allowing relative motion between two elements of a machine The two general classes of bearings are journal bearings, also known as sliding or plain surface bearings, and rolling element bearings, sometimes also

Diagnosing Differential Noise Know Your Parts

Rumbling or whirring at speeds over 20 mph can be caused by worn carrier bearings The noise may change while cornering or turning Regular clunking or loud clicking every few feet may indicate a broken ring or pinion gear tooth
