Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, tire inflator, and torque wrench.
Check each tire's pressure and inflate to the manufacturer's recommended PSI.
Inspect tires for uneven wear or damage; replace if necessary.
If the tires are unbalanced, take the vehicle to a tire shop for balancing.

3. Wheel Alignment and Suspension Inspection

Tools Required: Alignment machine or basic alignment tools.
Visually inspect the suspension components for any visible damage or excessive wear.
If misalignment is suspected, perform a wheel alignment using an alignment machine.

4. Driveshaft and CV Joint Inspection

Tools Required: Jack stands, socket set, and torque wrench.
Lift the vehicle and securely support it on jack stands.
Inspect the driveshaft and CV joints for any signs of damage or excessive play.
If any parts are damaged, replace them as necessary.
