Drive/Propeller Shaft: Testing and Inspection
Driveshaft Inspection
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 IN THE REAR JACK STORAGE AREA. FAILURE TO DO SO MAY RESULT IN UNEXPECTED INFLATION OR
DEFLATION OF THE AIR SPRINGS WHICH MAY RESULT IN SHIFTING OF THE VEHICLE DURING THESE OPERATIONS.
-
A VEHICLE EQUIPPED WITH A TRACTION-LOK DIFFERENTIAL WILL ALWAYS HAVE BOTH WHEELS DRIVING. IF, WHILE
THE VEHICLE IS BEING REPAIRED, ONLY ONE WHEEL IS RAISED OFF THE FLOOR AND THE REAR AXLE IS DRIVEN BY
THE ENGINE, THE WHEEL ON THE FLOOR COULD DRIVE THE VEHICLE OFF THE STAND OR JACK. BE SURE BOTH REAR
WHEELS ARE OFF THE FLOOR.
Inspect the driveshaft universal and constant velocity joints for proper operation
Place the vehicle on a frame hoist and rotate the driveshaft by hand. Check for excess play, rough operation or seized joints. Replace the U-joints if they
show signs of seizure, excessive wear, or improper seating.
Inspect the driveshaft slip yokes for excessive radial looseness and seizure. If these conditions exist, a 4x2 driveshaft slip yoke can be replaced.
Inspect the driveshaft for dents and missing balance weights.
