Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment such as gloves and eye protection.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Check tire pressure using the tire pressure gauge and inflate to manufacturer specifications.
Inspect tires for uneven wear patterns or damage; replace if necessary.
If tires need replacement, lift the vehicle using a jack and secure with jack stands.
Remove the lug nuts using the lug wrench and replace the tires as needed.

3. Suspension Component Check

Tools Required: Socket set, torque wrench
Use a socket set to inspect and tighten any loose suspension components, including control arms and strut mounts.
If any components are damaged, follow the removal and installation procedures for those specific parts.

4. Wheel Alignment

Tools Required: Alignment rack (professional service recommended)
After replacing tires and inspecting suspension, take the vehicle to a professional alignment shop to ensure proper wheel alignment.
Adjust camber, caster, and toe settings according to manufacturer specifications.

5. Verify Shock Absorber Function

Tools Required: Wrench set
Check for signs of fluid leakage on the shock absorbers; replace if leaking or worn.
To replace, use a wrench to remove the nuts securing the shocks and install new shocks, tightening to manufacturer's torque specifications.
