Solution

1. Tire Inspection

Sub-steps:
1. Remove hubcaps or wheel covers if applicable.
2. Inspect each tire for bulges, cuts, or uneven wear.
3. Measure tire pressure using a tire gauge and adjust to factory specifications.

2. Suspension Component Check

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect control arms, bushings, and strut mounts for signs of wear or damage.
3. Shake the wheels to check for excessive play in the bearings or suspension joints.

3. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or rust.
2. Check the CV joints for tears in the protective boots or signs of grease leakage.
3. Rotate the driveshaft by hand to feel for any binding or roughness.

4. Balancing and Alignment

Sub-steps:
1. Take the vehicle to a tire shop for balancing if tire issues are found.
2. Perform a wheel alignment to ensure proper tracking and to minimize vibration.

5. Replace Damaged Components

Sub-steps:
1. If any worn or damaged parts are identified during inspections, replace them with OEM or high-quality aftermarket parts.
2. Follow manufacturer specifications for torque settings when reinstalling components.
