Sub-steps:
1. Visually inspect tires for uneven wear patterns, bulges, or damage.
2. Measure tire pressure and inflate to the manufacturer's specifications (found on the driver’s door jamb).
3. If tires are damaged or excessively worn, replace them with new tires that match OEM specifications.

3. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.

3. Ensure that all alignment angles are adjusted to the manufacturer’s specifications.

4. Suspension Component Inspection and Replacement

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect all suspension components (control arms, bushings, struts) for signs of wear or damage.
3. Replace any worn or damaged components with OEM parts, ensuring proper torque specifications are followed during reassembly.

5. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for signs of rust, cracks, or excessive play.
2. Check CV joints for any signs of grease leakage or damage.
3. Replace any damaged driveshaft or CV joint with OEM parts as necessary.
