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. 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.

Inspect the driveshaft for any undercoating, physical damage and missing balance weights. Check for index marks (yellow paint daub marks) on the rear of the driveshaft and the axle pinion flange. The paint daubs must be less than 22-1/2 degrees apart.
