Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for visible damage or uneven wear on all four tires.
- Use a tire pressure gauge to ensure all tires are inflated to manufacturer specifications.
Replace Tires (if necessary):
- If tires are damaged or excessively worn, remove them using a jack and socket set.
- Install new tires, ensuring they are balanced properly, and torque the lug nuts to manufacturer specifications (typically around 100 lb-ft).

3. Drive Component Inspection

Inspect Driveshaft and CV Joints:
- Raise the vehicle and support it securely on jack stands.
- Visually inspect the driveshaft for any signs of wear, such as cracks or excessive play in the CV joints.
- If damaged, replace the driveshaft or CV joints as necessary.

4. Suspension Inspection

Check Suspension Components:
- Look for any loose or worn components, including control arms, bushings, and shocks.
- Tighten any loose bolts and replace any damaged components as needed.

5. Wheel Alignment

Perform Wheel Alignment:
- Use a professional wheel alignment tool to check the alignment settings.
- Adjust the alignment to meet manufacturer specifications, ensuring proper handling and tire wear.
