Wheel Bearing: Testing and Inspection
Front
DIAGNOSIS AND TESTING - HUB AND BEARING
The condition of the front hub and bearing assembly is diagnosed using the inspection and testing procedure.
The bearing contained in the Unit III front hub/bearing assembly will produce noise and vibration when worn or damaged. The noise will generally
change when the bearings are loaded. A road test of the vehicle is normally required to determine the location of a worn or damaged bearing.
Find a smooth level road surface and bring the vehicle up to a constant speed. When vehicle is at a constant speed, swerve the vehicle back and forth
from the left and to the right. This will load and unload the bearings and change the noise level. When bearing damage is slight, the noise is sometimes
noticeable at lower speeds and at other times is more noticeable at speeds above 105 km/h (65 mph).
