Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Jack up the vehicle and support it safely with jack stands.

2. Visual Inspection and Component Replacement

Inspect Components:
- Check control arms, bushings, struts, and shock absorbers for wear or damage.
- Look for any leaks in the struts or air suspension components.
Replace Damaged Parts:
- If any component is worn or damaged, follow these sub-steps:
- Control Arm Replacement:
  1. Remove the wheel and tire.
  2. Unbolt the control arm from the chassis and knuckle.
  3. Install the new control arm and torque bolts to manufacturer specifications.
- Strut Replacement:
  1. Disconnect the strut from the top mount and lower knuckle.
  2. Remove the strut assembly and replace it with a new strut.
  3. Reattach and torque all bolts to the specified values.

3. Air Suspension Repair (if applicable)

Check and Replace Air Lines:
1. Inspect air lines for cracks or leaks.
2. Replace damaged air lines with new ones, ensuring secure connections.
Compressor Inspection:
1. Test the air compressor for proper operation.
2. If faulty, disconnect and remove the compressor, then install a new one.
