Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Always wear safety glasses and gloves.

2. Tire Inspection and Balancing

Remove the wheel covers or hubcaps if equipped.
Loosen the lug nuts slightly using a socket set.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels and inspect tires for uneven wear or damage.
If tires are in good condition, mount them on a wheel balancer and check for balance.
If unbalanced, adjust weights accordingly and retest.

3. Suspension and Alignment Check

Visually inspect all suspension components (control arms, bushings, shock absorbers) for wear or damage.
If any components are damaged, replace them using the appropriate OEM parts.
Perform a four-wheel alignment using an alignment machine.
Adjust camber, caster, and toe settings to manufacturer specifications.

4. Drivetrain Inspection

Inspect the driveshaft and CV joints for any signs of wear or damage.
If any components are worn, replace them with OEM parts.
Ensure that all bolts and fasteners are tightened to the manufacturer’s torque specifications.
