Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery if working on electronic components.

2. Tire Inspection

Tools Required: Tire pressure gauge, tire tread depth gauge.
Check tire pressure and inflate to the recommended PSI.
Measure tread depth across the tire's surface; replace tires if tread is uneven or below 2/32 inch.

3. Shock Absorber Replacement

Tools Required: Socket set, torque wrench, jack stands, wheel chocks.
Raise the vehicle and secure it on jack stands.
Remove the wheel to gain access to the shock absorber.
Unbolt the upper and lower mounting points of the shock absorber.
Replace the old shock absorber with a new one, ensuring the new part is oriented correctly.
Torque the bolts to the manufacturer's specifications (typically around 30-50 lb-ft, but refer to service manual for specific values).
Reinstall the wheel and lower the vehicle.

4. Alignment and Balancing

Tools Required: Alignment rack, wheel balancing machine.
After replacing suspension parts, take the vehicle to a professional alignment shop.
Ensure that the front and rear wheels are properly aligned and balanced according to the manufacturer's specifications.
