Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Adjust Tires

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Check tire pressure; inflate to recommended PSI if low.
Visually inspect tires for uneven wear or damage.
If tires are damaged or worn unevenly, replace them.
Re-torque lug nuts to manufacturer's specifications after adjusting.

3. Check Suspension Components

Tools Required: Wrench set, socket set
Raise the vehicle using a jack and secure it with jack stands.
Inspect suspension components including control arms, bushings, and struts for wear or damage.
Replace any damaged components as necessary.
Ensure all bolts are tightened to manufacturer torque specifications.

4. Perform Wheel Alignment

Tools Required: Wheel alignment rack or alignment tools
Take the vehicle to a professional alignment technician or use alignment tools to adjust angles to specifications.
Confirm that the vehicle is tracking straight by taking it for a test drive.

5. Inspect Driveshaft and CV Joints

Tools Required: Torque wrench, socket set
Raise the vehicle and inspect the driveshaft for any signs of damage or imbalance.
Check CV joints for wear or tearing of rubber boots.
Replace any damaged or worn components and ensure all fasteners are tightened to proper torque values.
