Solution

1. Preparation

Tools Needed: Jack stands, socket set, torque wrench, pry bar, OBD-II scanner
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery before working on electrical systems.

2. Inspect and Replace CV Joints/Axles

Sub-steps:
1. Raise the vehicle securely using jack stands.
2. Remove the front wheels using a socket set.
3. Visually inspect the CV joints for torn boots or grease leakage.
4. If damaged, use a pry bar to detach the CV joint from the hub.
5. Replace with a new CV joint or axle as necessary, torqueing to the manufacturer's specifications (typically around 45-60 ft-lbs).
6. Reinstall the wheel and lower the vehicle.

3. Check and Replace Engine/Transmission Mounts

Sub-steps:
1. Locate the engine and transmission mounts.
2. Inspect for cracks, tears, or separation of the rubber.
3. If damaged, remove the bolts securing the mount using a socket set.
4. Replace the mount with a new one, ensuring all bolts are torqued to specifications (usually around 30-50 ft-lbs for mounts).

4. Inspect Suspension Components

Sub-steps:
1. Check the condition of the struts, springs, and bushings visually.
2. Use a pry bar to test for play in the suspension components.
3. Replace any worn or damaged parts as necessary, ensuring all fasteners are torqued to specification.
