Mechanism of injury. The differential side gears and pinions can be checked by turning the vehicle. They usually do not cause noise during the avant-garde movement when unloading gear. Side gears are loaded during the twists and turns of the vehicle. Worn pinion shaft can also cause binding or knocking noise. Bearing noise bearings, shaft, differential and axle gear may produce noise if worn or damaged. Bearing noise may be whining, growling sound. Pinion bearings have a constant field. This noise is only changed when the speed of the vehicle. Pinion bearing noise will be higher pitched because it rotates more rapidly. Drive the car and load differential. If the bearing noise occurs, the pinion rear bearing is the source of the noise. If the bearing noise heard during the coast bearing the front gears is the source. Worn or damaged differential bearings normally produce noise low.
Differential bearing noise similar to the noise of the gear. Step differential bearing noise is constant depends only on the speed of the vehicle. Axle shaft bearings produce noise and vibrations when worn or damaged. The noise usually changes when loading the bearings. Road test the vehicle. Turn the car sharply to the left and right. This will load the bearings and change the level of noise. Where the minor axis, given the damage, the noise is usually not noticeable at speeds of 30 mph above. low detonation velocity of low detonation velocity is usually caused by wear crosses or worn side gear bearing ring. Worn pinion shaft bore is also a cause of low speed knock. VIBRATION vibration on the rear face of the vehicle, usually caused by a damaged drive shaft. There is no drive shaft balance value. Worn or balance wheel. Loose wheel lug nuts. Be a U-joint (s). Loose/broken coil springs. Damage to the axle shaft bearing (s). 2001 Dodge Ram 2500 bearing noise testing and verification Download
