Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery if any electrical components will be removed.

2. Tire Balancing

Remove the front wheels using a socket set.
Mount the tires on a wheel balancer.
Adjust weights as needed to achieve proper balance.
Reinstall the balanced wheels and torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).

3. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust the camber, caster, and toe settings according to manufacturer specifications.
Test drive the vehicle to ensure alignment is correct.

4. Suspension Inspection and Repair

Visually inspect tie rods, control arms, and bushings for any signs of wear or damage.
If any component is damaged, remove and replace it:
- For tie rods, detach the outer tie rod end from the steering knuckle.
- Replace with new tie rod and adjust to manufacturer specs.
Reassemble all components securely and torque to specifications.
