Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather all necessary tools and parts to facilitate repairs.
Safety gear: gloves and safety glasses.

2. Tire Inspection and Balancing

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's specifications.
Visual Inspection: Look for any visible damage on the tires. Replace any damaged tires.
Balance and Alignment: If tires are damaged or worn, replace them. Then, take the vehicle to a professional shop for balancing and alignment.

3. Inspect Driveshaft and CV Joints

Remove Drive Axles: Using a socket set, remove the bolts securing the drive axles to the wheel assembly.
Inspect CV Joints: Check for any tears in the rubber boots and listen for clicking noises while rotating the joint. Replace if damaged.
Reinstall Axles: Reattach the drive axles, ensuring to torque bolts to the manufacturer’s specifications.

4. Check Engine and Transmission Mounts

Visual Inspection: Look for cracks, tears, or excessive wear in the mounts.
Replacement: If damaged, remove the old mounts using a socket set and replace them with new mounts. Torque to specifications.

5. Suspension Inspection

Visual Inspection: Check struts, shocks, and bushings for wear and damage.
Replacement: If any components are worn, remove the damaged parts and replace them with new ones. Torque to specifications.
