Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Locate the engine and transmission mounts (usually found near the engine block and transmission).
2. Use a socket set to remove the bolts securing the mounts.
3. Carefully lift the engine/transmission slightly to relieve pressure on the mounts.
4. Remove the damaged mounts and replace them with new ones, ensuring they are oriented correctly.
5. Torque the bolts to manufacturer specifications (typically 40-60 ft-lbs).

3. Inspect and Replace CV Joints/Axles

Sub-steps:
1. Remove the front wheels using a lug wrench.
2. Detach the axle nut and any retaining clips if present using appropriate tools.
3. Pull the axle out of the hub and inspect the CV joints for wear or torn boots.
4. Replace the CV axle if damage is found.
5. Reassemble by inserting the new axle and securing with the axle nut, torquing to manufacturer specifications (usually 150 ft-lbs).

4. Inspect and Repair Suspension Components

Sub-steps:
1. Inspect struts and shocks for leaks or damage.
2. Check control arms and bushings for excessive play or wear.
3. Replace worn components as necessary, following the specific removal and installation procedures outlined in the service manual.
4. Ensure all fasteners are torqued to specifications.
