Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repairs.

2. Tire Inspection and Replacement

Check tire pressure and inflate to the manufacturer's recommended levels.
Inspect tires for uneven wear or damage; replace if necessary.
If tires are worn, remove them using a socket set to loosen lug nuts.
Install new tires and torque lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Perform a wheel alignment if tire wear is irregular.

3. Drivetrain Inspection

Lift the vehicle using a jack and secure it with jack stands.
Inspect the driveshaft for any signs of damage or imbalance.
Check the motor mounts for wear; replace if soft or cracked.
Tighten or replace any loose bolts found in the drivetrain.
If necessary, replace the driveshaft or components based on inspection findings.

4. Suspension Inspection

Inspect suspension components including control arms and bushings for signs of wear or damage.
Replace any worn or damaged bushings and components.
Tighten any loose suspension bolts to manufacturer's torque specifications.
