Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Inspect all tires for uneven wear patterns; replace tires if tread is worn beyond 2/32 inch.
2. Check tire pressure and inflate to the manufacturer’s recommended PSI.
Tools Required: Tire pressure gauge, jack, jack stands, tire iron.

3. Shock Absorber/Strut Replacement

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the shocks/struts.
3. Unbolt the top mount and bottom mount of the shock/strut assembly.
4. Replace with new shocks/struts and torque bolts to manufacturer specifications (typically around 25-30 ft-lbs for top mounts, and 45-50 ft-lbs for bottom mounts).
5. Reinstall the wheel and lower the vehicle.
Tools Required: Socket set, torque wrench, spring compressor (if replacing struts).

4. Wheel Alignment

Sub-steps:
1. After replacing components, take the vehicle to a professional alignment shop.
2. Ensure that the alignment settings meet the manufacturer's specifications.
Tools Required: Alignment rack (professional service).

5. Additional Component Inspection (if necessary)

Sub-steps:
1. Inspect sway bar links and bushings for wear; replace as needed.
2. Check control arm bushings; replace if cracked or worn.
Tools Required: Socket set, torque wrench.
