Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, alignment tools, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure in all four tires.
- Adjust to manufacturer specifications found on the driver’s door jamb.
Inspect Tires:
- Look for uneven wear patterns, bulges, or cuts.
- Replace tires if they are worn beyond legal limits or show damage.

3. Wheel Alignment

Perform Wheel Alignment:
- Follow the manufacturer’s specifications for alignment angles.
- Adjust toe, caster, and camber as necessary using alignment machine.
- Torque all components to specification after adjustments.

4. Suspension Inspection and Repair

Inspect Suspension Components:
- Check shocks and struts for leaks and physical damage.
- Replace worn or damaged components as needed.
Replace Bushings:
- If any bushings are cracked or deteriorated, remove and replace them.
- Use a bushing removal tool for ease of access.

5. Steering System Check

Test for Play in Steering:
- Check tie rods and rack and pinion for looseness.
- Tighten or replace any components that exhibit excessive play.
Reassemble and Torque:
- Ensure all fasteners and components are torqued to specifications.
