Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues during repair.

2. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Remove all four tires using a socket set.
2. Inspect each tire for uneven wear patterns and check the tread depth.
3. Replace any badly worn tires with OEM or premium replacement tires.
4. Balance the tires and reinstall them, ensuring to torque the lug nuts to the manufacturer's specifications (typically 100-120 ft-lbs).

3. Suspension Component Inspection and Replacement (if necessary)

Sub-steps:
1. Visually inspect the control arms, struts, and bushings for signs of wear or damage.
2. If any components are damaged, remove them using the appropriate socket set.
3. Replace with OEM or high-quality aftermarket parts.
4. Reinstall components and torque to manufacturer specifications.

4. Driveshaft and CV Joint Inspection

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Inspect the driveshaft for any visible cracks or damage.
3. Check the CV joints for excessive play or torn boots.
4. Replace any damaged driveshaft or CV joints, using an appropriate torque wrench to secure fasteners.

5. Engine and Transmission Mount Inspection

Sub-steps:
1. Inspect engine and transmission mounts for cracks or signs of wear.
2. If mounts are damaged, remove the old mounts using a socket set.
3. Install new mounts, ensuring they are torqued to the manufacturer’s specifications.
