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.

CAUTION: Pinion bearing preload must be reset if the pinion nut has been loosened or removed for companion flange re-indexing or replacement.

1.Raise the vehicle on a twin-post hoist that supports the rear axle.
2.Remove the driveshaft.
3.Check the companion flange for damage.

7.Position the Dial Indicator/Magnetic Base as shown. Turn the Companion Flange Runout Gauge, and locate and mark the high spot on the companion flange with yellow paint.

If the flange runout exceeds 0.25 mm (0.010 inch), remove the companion flange, re-index the flange one-half turn on the pinion, and reinstall it.

8.Check the runout again. If necessary, rotate the flange until an acceptable runout is obtained. If the flange runout is still more than 0.25 mm (0.010 inch), replace the companion flange.
9.If excessive runout is still evident after replacement of the companion flange, replace the ring and pinion. Repeat the above checks until the runout is within specifications.
10.Install the driveshaft.

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.

CAUTION: Pinion bearing preload must be reset if the pinion nut has been loosened or removed for companion flange re-indexing or replacement.
