Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Tire Inspection and Replacement

Inspect Tires
- Check for uneven wear, bulges, or foreign objects.
- Measure tire pressure and adjust to manufacturer specifications.
Replace Tires (if necessary)
- Use a jack to lift the vehicle.
- Remove the lug nuts with a socket wrench and take off the tire.
- Install new tires and torque lug nuts to manufacturer specifications (usually around 100-150 ft-lbs).

3. Suspension Component Replacement

Inspect and Replace Worn Components
- Check control arms, bushings, and ball joints for wear.
- If damaged, use a socket set to remove the old components and install new ones, ensuring they are torqued to manufacturer specifications.

4. Driveshaft Inspection and Repair

Inspect Driveshaft
- Examine for any visible damage or imbalance.
- If damaged, remove the driveshaft by unbolting it from the rear differential and transmission.
- Replace with a new driveshaft if necessary, and torque bolts to specifications.

5. Mounts Inspection and Replacement

Check Engine and Transmission Mounts
- Visually inspect for cracks or excessive wear.
- If replacement is needed, unbolt the mounts using a socket wrench, install new mounts, and torque to specifications.
