Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Tires (if needed)

Inspect Tires:
- Check tire pressure using a tire pressure gauge. Inflate to manufacturer specs if low.
- Visually inspect for cuts, bubbles, or uneven wear.
Replace Tires:
- If tires are damaged or excessively worn, remove them using a socket set.
- Install new tires, ensuring they are properly seated on the rims.
- Torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Wheel Balancing

Balance Wheels:
- Remove the wheel from the hub and place it on the wheel balancer.
- Follow the machine’s instructions to adjust weights until the wheel is balanced.
- Reinstall the balanced wheel and torque the lug nuts.

4. Suspension Inspection and Repair

Inspect Components:
- Visually check tie rods, control arms, and bushings for wear.
Replace Worn Components:
- If any parts are worn, use a socket set to remove and replace them with new OEM parts.
- Ensure all fasteners are tightened to the specified torque.

5. Wheel Alignment

Perform Alignment:
- Use an alignment machine to measure the angles of the wheels.
- Adjust caster, camber, and toe angles to meet manufacturer specifications.

6. Final Checks

Test Drive:
- After completing repairs, conduct a test drive at highway speeds to ensure the issue is resolved.
