Solution

1. Tire Balancing

Tools Required: Wheel balancing machine, torque wrench.
Sub-steps:
1. Remove the wheel from the car using a socket set.
2. Mount the wheel on the balancing machine.
3. Follow the machine's instructions to identify any imbalance.
4. Attach wheel weights as determined by the machine to correct the balance.
5. Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).

2. Alignment Adjustment

Tools Required: Alignment machine, torque wrench.
Sub-steps:
1. Position the vehicle on an alignment rack.
2. Measure the current alignment angles (camber, caster, toe).
3. Adjust the tie rod ends to bring the toe settings back to factory specifications.
4. Recheck all angles to ensure they are within the specified range.
5. Perform a road test to confirm steering stability.

3. Suspension Inspection and Repair

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar.
Sub-steps:
1. Raise the front of the vehicle using a jack and secure with jack stands.
2. Visually inspect suspension components for wear or damage.
3. If any components are damaged (control arms, bushings, or tie rods), replace them as needed.
4. Reassemble any components removed for inspection and torque to manufacturer specifications.
