Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it using a jack and jack stands.

2. Tire Inspection and Replacement

Inspect Tires:
- Check tire pressure with a gauge; inflate or deflate as needed to manufacturer's specifications.
- Examine tread depth using a tread depth gauge; replace tires if they are worn below the legal limit.
Replace Tires (if necessary):
- Remove the wheel lug nuts using a socket wrench.
- Replace the tire and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically around 76-85 ft-lbs).

3. Suspension Component Inspection and Replacement

Inspect and Replace Shocks/Struts (if worn):
- Remove the wheel to access the suspension components.
- Unbolt the top and bottom mounting points of the shock/strut using a socket set.
- Replace with new shocks or struts, ensuring they are torqued to specifications.

4. Wheel Alignment

Perform Wheel Alignment:
- Take the vehicle to a professional alignment shop or use an alignment tool.
- Adjust camber, toe, and caster angles to meet the manufacturer's specifications.

5. Final Inspection

Check for Loose Components:
- Inspect all undercarriage components for tightness and condition.
- Tighten any loose bolts or replace damaged parts as necessary.
