1. WARNING: The electrical power to the air suspension system must be turned off prior to hoisting, jacking or towing an air suspension vehicle. 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.
2. Raise and support the vehicle.
3. Inspect the catalytic converter for loose or missing heat shields.





4. Install worm clamps for heat shields that are loose.
^ Use one of the following clamps: F0TZ-5A231-A or W705949-S300.
^ Trim off the excess ear of the worm clamp.
5. If the heat shields are missing, install new heat shields. If new heat shields are not available, install a new catalytic converter.
