Wheel Bearings Diagnosis

Wheel Bearings Diagnosis:






CAUTION: front wheel drive vehicles, drive wheel spin should be limited to 35 mph as indicated on the speedometer. This limit is necessary because the speedometer only Indicates one-half of the actual wheel speed when one drive wheel is spinning and the other drive wheel Is stopped. Unless care is taken In limiting drive wheel spin, the spinning wheel can reach excessive speeds. This can result in possible tire disintegration or differential failure, which could cause serious personal injury or extensive vehicle damage.
