Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.

2. Tire Inspection and Replacement

Check Tire Pressure
- Use a tire pressure gauge to measure each tire's pressure.
- Adjust any tires that are found to be under-inflated or over-inflated to the recommended PSI.
Inspect Tires for Damage
- Visually examine each tire for bulges, cuts, or foreign objects.
- If damage is found, replace the affected tire with a new tire of the same specifications.

3. Wheel Balancing

Remove Wheels
- Loosen the lug nuts using a socket set and remove the wheels from the vehicle.
Balance Each Wheel
- Mount each wheel on a wheel balancer.
- Add weights as necessary to achieve balance.
Reinstall Wheels
- Torque the lug nuts to the manufacturer’s specified torque value.

4. Suspension Inspection and Repair

Visual Inspection
- Inspect suspension components for signs of wear or damage.
Replace Worn Components
- If any components are found damaged (e.g., bushings, control arms), replace them with OEM parts.

5. Wheel Alignment

Perform Wheel Alignment
- Use a professional alignment machine to check and adjust the alignment settings to the manufacturer’s specifications.
