Tools Required: Socket set, wrenches, air line removal tool, torque wrench.
Sub-steps:
1. Raise the vehicle and support it securely on jack stands.
2. Remove the wheel associated with the faulty air bag.
3. Disconnect the air line from the air bag using an air line removal tool.
4. Unbolt and remove the old air bag from the suspension assembly.
5. Install the new air bag, ensuring it is properly seated and secured with the appropriate torque specifications.
6. Reconnect the air line to the new air bag.

3. Repair or Replace Compressor

Tools Required: Socket set, multimeter, basic hand tools.
Sub-steps:
1. Locate the air compressor and check for any visible damage or leaks.
