Solution

1. Preparation

Gather tools and materials including a socket set, jack stands, and a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Replace Tires (if necessary)

Inspect Tires:
- Check for uneven wear, bulges, or foreign objects.
Replace Tires:
- Remove the wheel using a socket set.
- Install new tires, ensuring they match the original specifications.
- Torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Balance Wheels

Use a wheel balancer to check and adjust the balance of each wheel.
Ensure weights are evenly distributed and secure.

4. Inspect and Replace Driveshaft/CV Joints

Remove Driveshaft:
- Raise the vehicle and secure it with jack stands.
- Remove bolts securing the driveshaft using a socket set.
Inspect CV Joints:
- Check for torn boots or excessive play.
Replace if necessary:
- Install new CV joints and secure the driveshaft with new bolts, torquing to specifications.

5. Examine Suspension Components

Check Control Arms and Bushings:
- Inspect for cracks or excessive play.
- Replace any worn components.
Inspect Struts:
- Look for oil leaks or physical damage.
- Replace struts if necessary, ensuring proper torque on bolts.

6. Check and Replace Engine/Transmission Mounts

Inspect Mounts:
- Look for cracks or separation in the rubber.
Replace Mounts:
- Remove the bolts securing the mounts and replace with new mounts.
- Torque the bolts to specifications.
