Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery for electrical safety.

2. Wheel Alignment

Lift the Vehicle: Use a hydraulic lift or jack to elevate the vehicle.
Remove Wheels: Use a socket set to take off the lug nuts and remove the wheels.
Align the Wheels: Follow the wheel alignment machine instructions to adjust the angles.
Reinstall Wheels: Place the wheels back on and tighten lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Tire Inspection and Replacement

Inspect Tires: Check for uneven wear, bulges, or cuts. Measure tread depth.
Replace Tires if Necessary: If tires are worn beyond legal limits, replace them with OEM or high-quality alternatives.
Balance Tires: Have the tires balanced at a professional shop.

4. Drivetrain Inspection

Examine Driveshaft: Visually inspect for cracks or excessive play in the u-joints.
Replace Damaged Parts: If damage is found, replace the driveshaft or CV joints as needed.

5. Engine and Transmission Mounts

Inspect Mounts: Look for cracks or deterioration in engine and transmission mounts.
Replace Mounts: Remove failing mounts using a socket set and replace with OEM parts.
