Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection

Check tire pressure with a tire gauge; inflate to recommended PSI if low.
Inspect tires for uneven wear patterns; replace if necessary.
Rotate tires if uneven wear is found to ensure even distribution.

3. Wheel Balancing and Alignment

Remove wheel covers or hubcaps if applicable.
Use a wheel balancer to check and correct tire balance.
Perform a four-wheel alignment using an alignment machine, adjusting the camber, caster, and toe as needed.

4. Suspension Component Inspection

Visually inspect control arms, bushings, and shocks for any signs of wear or damage.
Replace any worn or damaged components using appropriate torque specifications.
Ensure all bolts and nuts are tightened to the manufacturer's specifications.

5. Driveshaft and CV Joint Inspection

Inspect the driveshaft for any visible damage or excessive play.
If any issues are found, replace the driveshaft or CV joints as necessary.
Reassemble and ensure all fasteners are properly torqued.
