Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Tire Inspection and Replacement

Remove the wheel covers or hubcaps (if applicable).
Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels and inspect for damage, bulges, or uneven wear.
Replace any damaged tires with new ones of the same specifications.
Reinstall wheels and hand-tighten lug nuts before lowering the vehicle.

3. Wheel Balancing

Mount the wheels on a wheel balancer.
Spin the wheels to identify any imbalance.
Add wheel weights as necessary to achieve balance.
Reinstall the balanced wheels on the vehicle, ensuring lug nuts are torqued to manufacturer specifications (typically 80-100 ft-lbs).

4. Driveshaft and CV Joint Inspection

Inspect the driveshaft for any signs of damage or excessive play.
Check the CV joints for wear by attempting to move them and listening for clicks or pops.
Replace any worn or damaged parts as necessary.

5. Wheel Alignment

Use an alignment machine to measure the alignment angles of all four wheels.
Adjust the camber, caster, and toe settings to meet manufacturer specifications.
Test drive the vehicle to confirm alignment settings.
