Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect Tires

Sub-steps:
- Use a tire pressure gauge to check and adjust tire pressures to manufacturer specifications.
- Measure tire tread depth using a tread depth gauge; replace tires if they are below the recommended depth.
Tools Required: Tire pressure gauge, tread depth gauge.

3. Check Suspension Components

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Visually inspect shocks and struts for oil leaks or physical damage.
- Check all bushings and mounting points for wear or degradation.
Tools Required: Jack, jack stands, flashlight.

4. Perform Wheel Alignment

Sub-steps:
- Use a professional wheel alignment machine or take the vehicle to a certified alignment shop.
- Adjust camber, caster, and toe angles according to manufacturer specifications.
Tools Required: Alignment machine (if doing it yourself).

5. Replace Worn Components (if necessary)

Sub-steps:
- If any suspension components are damaged, remove the old parts using appropriate wrenches and sockets.
- Install new parts and torque them to manufacturer specifications.
Tools Required: Socket set, torque wrench.
