Wheel Bearing: Testing and Inspection
1. Raise the vehicle until the tire is off the floor.
WARNING: THE ELECTRICAL POWER TO THE AIR SUSPENSION SYSTEM MUST BE SHUT OFF PRIOR TO HOISTING,
JACKING OR TOWING AN AIR SUSPENSION VEHICLE. THIS CAN BE ACCOMPLISHED BY TURNING OFF THE AIR
SUSPENSION SWITCH LOCATED BEHIND THE RH KICK PANEL AREA. FAILURE TO DO SO CAN RESULT IN
UNEXPECTED INFLATION OR DEFLATION OF THE AIR SPRINGS, WHICH CAN RESULT IN SHIFTING OF THE VEHICLE
DURING THESE OPERATIONS.
2. Grasp each front tire at the top and bottom and move the wheel inward and outward while lifting the weight of the tire off the front wheel bearing.
NOTE: Make sure the wheel rotates freely and the brake pads are retracted sufficiently to allow movement of the tire and wheel assembly.
3. If the tire and wheel (hub) is loose on the wheel spindle or does not rotate freely, adjust the front wheel bearings.
