Solution

1. Tire Inspection and Replacement

Check Tire Pressure
- Use a tire pressure gauge to measure each tire’s pressure.
- Inflate tires to recommended specifications as noted on the driver’s side door jamb.
Inspect Tires
- Look for bulges, cracks, or punctures.
- If any damage is found, replace the affected tire(s).

2. Wheel Balancing

Remove Wheels
- Loosen lug nuts and lift the vehicle using a jack.
- Remove the wheels using a socket set.
Balance Wheels
- Mount the wheels on a balancing machine to determine if they are unbalanced.
- Add weights as necessary to achieve balance.
Reinstall Wheels
- Torque the lug nuts to the manufacturer’s specifications (typically 80-100 lb-ft) using a torque wrench.

3. Wheel Alignment

Perform Wheel Alignment
- Use a wheel alignment machine to check and adjust alignment settings for toe, camber, and caster angles.
- Adjust the suspension components as needed to bring them into alignment.

4. Inspect and Replace Suspension Components (if necessary)

Inspect Suspension
- Check all suspension parts, including tie rods and bushings, for wear and damage.
Replace Damaged Components
- If any components are worn, replace them.
- Follow the manufacturer’s specifications for installation torque and adjustments.
