Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and apply the parking brake.
Disconnect the battery (if working on electrical components).

2. Tire Inspection and Replacement

Inspect Tires
- Check for any visible damage or uneven wear.
- Use a tire depth gauge to measure tread depth.
Replace Tires (if necessary)
- Remove the wheel lug nuts using a socket set.
- Lift the vehicle with a jack and secure it with jack stands.
- Replace any damaged tires with new ones, ensuring they match the specifications.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 75-100 ft-lbs).

3. Wheel Balancing

Balance the Wheels
- Remove the wheels from the vehicle.
- Take the wheels to a tire shop or use a wheel balancer.
- Ensure weights are applied appropriately to balance the wheels.
- Reinstall the balanced wheels back onto the vehicle.

4. Suspension Check and Repair

Inspect Suspension Components
- Check control arms, bushings, and struts for wear or damage.
Replace Damaged Components
- If any components are worn, remove them using appropriate tools (socket set, wrenches).
- Install new parts, ensuring they are torqued to the manufacturer's specifications.

5. Wheel Alignment

Perform Wheel Alignment
- Use a professional alignment machine to adjust the toe, camber, and caster angles as per manufacturer specifications.
- Ensure proper alignment is achieved to prevent uneven tire wear and improve handling.
