Solution

1. Preparation

Gather tools such as a jack, jack stands, wrench set, and pry bar.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access suspension components.
3. Inspect control arms, bushings, and struts for wear and damage.
4. Replace any worn or damaged components with OEM or high-quality aftermarket parts.
5. Reassemble all parts and wheels, ensuring proper torque specifications (typically around 80-100 ft-lbs for wheel lug nuts).

3. Check and Replace Engine Mounts

Sub-steps:
1. Locate and inspect the engine mounts for cracks or excessive wear.
2. If damaged, remove the bolts securing the mount to the engine and the chassis.
3. Install the new engine mount, ensuring it is properly aligned.
4. Torque the bolts to the manufacturer's specifications (typically around 40-60 ft-lbs).

4. Inspect and Replace Driveline Components

Sub-steps:
1. Inspect CV joints and boots for tears or damage.
2. If the CV joint is damaged, remove the axle from the vehicle.
3. Replace the CV joint or entire axle assembly as needed.
4. Reinstall the axle and torque the axle nut to specifications (usually around 150-180 ft-lbs).
