Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the wheel covers or hubcaps (if applicable).
2. Loosen the lug nuts slightly while the vehicle is on the ground.
3. Use a jack to lift the vehicle and secure it with jack stands.
4. Remove the lug nuts and take off the wheel.
5. Inspect the tire for damage (bulges, cuts) and check tread depth.
6. Replace the tire if it is damaged or excessively worn.
7. Reinstall the wheel and lug nuts, torque them to manufacturer specifications (typically 80-100 ft-lbs).
8. Lower the vehicle and recheck tire pressure.

3. Suspension Component Repair/Replacement

Sub-steps:
1. Remove the necessary undercarriage covers to access the suspension.
2. Inspect control arms, bushings, and shocks for signs of wear.
3. If any components are damaged, remove and replace them. Use appropriate tools like a socket set and torque wrench to ensure correct installation.
4. For bushings, use a press to remove and install new bushings.
5. Reassemble any covers removed, ensuring all fasteners are tightened to specifications.

4. Drivetrain Inspection and Repair

Sub-steps:
1. Inspect the driveshaft and CV joints for any visible damage.
2. If there is play, remove the driveshaft and inspect the U-joints.
3. Replace any damaged components with OEM parts.
4. Reinstall the driveshaft and ensure it is torqued correctly.
