Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery (if needed) for safety when working on electronic components.

2. Tire Inspection and Replacement

Check Tire Pressure:
- Use a tire pressure gauge to ensure tires are inflated to the manufacturer's specifications (usually found on the driver's side door jamb).
Inspect Tread Depth:
- Use a tread depth gauge to measure the depth. Replace tires if they are below 2/32 inch.
Replace Tires (if necessary):
- Jack up the vehicle and remove the wheels.
- Install new tires ensuring they are properly balanced and torqued to specifications (usually around 100-120 ft-lbs).

3. Suspension Component Inspection and Replacement

Inspect Shocks/Struts:
- Remove any covers or shields to access the shock/strut assembly.
- Inspect for leaks and wear.
Replace Worn Shocks/Struts:
- Unscrew the top mounting bolts and lower bolts to remove the assembly.
- Install new shocks/struts using the manufacturer’s torque specifications.

4. Wheel Alignment

Perform Wheel Alignment:
- Use a professional alignment machine to adjust the camber, caster, and toe settings to factory specifications.

5. Final Check

Test Drive:
- Conduct a test drive to assess the ride quality and ensure no further issues are present.
