Driveline Noise

Driveline noises may baffle even the best technician. Vehicle noises coming from the tires, transmission, propeller shaft, universal joints and front or rear wheel bearings are often mistaken for axle noise. Such practices as raising tire pressure to eliminate tire noise (although this will not silence tread noise of mud- and snow tires) or listening for the noise at varying speeds and road surfaces (in drive, float and coast conditions) will aid in locating the source of alleged axle noises; Every effort should be made to isolate the noise to a specific driveline component instead of making a random guess that could be a costly waste of time.
