Axle Shaft: Service and Repair
Axle ShaftRemoval
1. WARNING: When equipped with rear air springs, 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 LH side of the luggage compartment. 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.
Turn the air suspension switch off.
