Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, tire pressure gauge, wheel balancing machine, alignment rack.
Safely park the vehicle on a flat surface and engage the parking brake.

2. Tire Inspection and Replacement

Remove the wheel covers or hubcaps if necessary.
Loosen the lug nuts slightly (do not remove completely).
Lift the vehicle using the jack and support it with jack stands.
Remove the lug nuts and take off the wheel.
Inspect the tire for bulges or uneven wear.
If necessary, replace the tire with a new one that matches the specifications.

3. Wheel Balancing

Mount the wheel on the wheel balancing machine.
Follow the machine’s instructions to balance the wheel.
Add weights as indicated by the machine to achieve balance.
Reinstall the balanced wheel back onto the vehicle.
Torque the lug nuts to the manufacturer's specifications.

4. Wheel Alignment

Drive the vehicle to a professional alignment shop or use an alignment rack if available.
Follow the alignment procedure to ensure the wheels are aligned to the manufacturer’s specifications.
Adjust camber, caster, and toe as required.

5. Suspension and Drivetrain Inspection

Inspect the suspension components (control arms, bushings, struts) visually for wear or damage.
Replace any worn parts with OEM or equivalent quality replacements.
Check the driveshaft and CV joints for any play or damage; replace if necessary.
