Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is cool to the touch before working on tires and suspension.

2. Tire Inspection and Adjustment

Inspect Tire Pressure:
- Use a tire pressure gauge to check the pressure of all tires.
- Inflate any under-inflated tires to the manufacturer's recommended PSI.
Inspect Tire Condition:
- Examine tires for any visible damage, bulges, or uneven wear.
- Rotate tires if uneven wear is detected to promote even wear.

3. Alignment Adjustment

Prepare for Alignment:
- Ensure the vehicle is on a wheel alignment rack.
- Confirm that the steering wheel is centered.
Perform Alignment:
- Follow the alignment machine instructions to adjust camber, caster, and toe settings to manufacturer specifications.
- Tighten all alignment adjustments to the specified torque values.

4. Suspension Component Replacement (if necessary)

Inspect and Replace Components:
- Check for worn out or damaged suspension components such as control arms, bushings, or tie rods.
- If damage is found, remove the old component using a socket set and replace it with a new one, ensuring proper torque specifications are met.
