Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Balancing

Sub-steps:
1. Remove the wheel caps (if applicable) and loosen the lug nuts on the affected wheels.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheels using a socket set.
4. Mount the wheels on a wheel balancer and check for imbalances.
5. Add weights as needed to balance the wheels correctly.
6. Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. After balancing, perform a wheel alignment using an alignment machine.
2. Adjust the camber, caster, and toe settings to meet manufacturer specifications.
3. Test drive the vehicle again to ensure that the steering is centered and does not pull to one side.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect and replace any worn suspension components (e.g., bushings, shocks, struts).
2. Check for any loose bolts or parts in the suspension system.
3. Tighten or replace components as necessary.
