Solution

1. Preparation

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

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, tire iron, jack, jack stands.
Sub-steps:
1. Check tire pressure using the tire pressure gauge and inflate to the manufacturer's recommended PSI if necessary.
2. Inspect tire tread for uneven wear patterns; replace any worn or damaged tires.
3. Remove each wheel using the tire iron and inspect the inner fender area for any debris or damage.

3. Suspension Component Inspection and Replacement

Tools Required: Wrench set, socket set, torque wrench, spring compressor (if needed).
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect the struts and shocks for leaks or damage; replace if necessary.
4. Check bushings and mounts for wear; replace any that are cracked or deteriorating.
5. Reassemble the suspension components, ensuring all bolts are torqued to manufacturer specifications.

4. Alignment Adjustment

Tools Required: Alignment tools (if performing in-house) or take to a professional.
Sub-steps:
1. If any suspension components were replaced, perform a four-wheel alignment.
2. Adjust camber, caster, and toe settings to manufacturer specifications.
3. Test drive the vehicle to ensure proper handling.
