Solution

1. Preparation

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

2. Tire Inspection

Tools Required: Tire pressure gauge, tread depth gauge.
Check each tire's pressure and inflate to the recommended PSI.
Measure tread depth; replace tires if they are worn unevenly or below the safe tread depth (2/32 inches).

3. Wheel Alignment

Tools Required: Alignment machine.
Position the vehicle on the alignment rack and follow the manufacturer's procedure to measure alignment angles (camber, caster, toe).
Adjust as necessary to bring angles within manufacturer specifications.

4. Suspension Component Inspection

Tools Required: Jack, jack stands, wrench set, torque wrench.
Raise the vehicle and secure on jack stands.
Inspect all suspension components: look for play in tie rods and ball joints, cracks in bushings, and any signs of wear.
Replace any worn or damaged components as needed, ensuring to torque bolts to manufacturer specifications.

5. Steering System Check

Tools Required: Wrench set, steering wheel puller (if needed).
Inspect the steering column for any loose connections or excessive play.
Tighten or replace components as necessary.
