Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and parked safely.
Disconnect the negative battery terminal if electrical components will be affected.

2. Tire Inspection and Replacement

Remove the Wheels
- Loosen the lug nuts with a socket wrench.
- Elevate the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheels.
Inspect Tires
- Check for any bulges, punctures, or excessive wear.
- If any tire is damaged, replace it with a new one.
Rebalance Tires
- Mount the tires on a wheel balancer.
- Adjust weights as necessary to achieve balance.
Reinstall Wheels
- Place the wheels back on the vehicle.
- Hand-tighten the lug nuts, then lower the vehicle back to the ground.
Torque Lug Nuts
- Use a torque wrench to tighten lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs for most vehicles).
- Recheck the torque after a short test drive.

3. Suspension Inspection and Repair

Inspect Suspension Components
- Visually examine shock absorbers, struts, and control arms for signs of wear or damage.
- If any component is damaged, replace it according to manufacturer specifications.
Alignment Check
- Use an alignment machine to check the wheel alignment.
- Adjust alignment settings to factory specifications if necessary.
