Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety glasses and gloves should be worn.

2. Tire Balancing

Remove the wheels from the vehicle using a socket set.
Mount the tires on a wheel balancer to identify heavy spots.
Attach weights to the rim according to the balancer's recommendations.
Reinstall the balanced wheels on the vehicle, ensuring lug nuts are torqued to 80-100 lb-ft.

3. Tire Replacement (if necessary)

If tires are found to be damaged or excessively worn, replace them.
Ensure the new tires match the vehicle's specifications for size and type.
Install new tires following the same process as balancing.

4. Suspension Inspection

Inspect control arms, bushings, and struts for signs of wear or damage.
Replace any worn components using a socket set and torque bolts to manufacturer specifications.
Reinstall all removed components securely.

5. Wheel Alignment

After ensuring tires and suspension are in good condition, perform a wheel alignment.
Adjust the angles using an alignment machine to manufacturer specifications.
Test drive the vehicle to confirm the alignment adjustments have resolved any steering issues.
