Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, pry bar, safety glasses.
Safety Warnings: Ensure the vehicle is on a level surface and properly secured with jack stands before working underneath.

2. Addressing Engine Mount Issues

Remove Engine Cover (if applicable):
- Use a socket set to unfasten any bolts securing the engine cover.
- Lift and set the cover aside.
Inspect Engine Mounts:
- Visually check mounts for cracks or excessive wear.
- Use a pry bar to gently lift the engine to assess mount integrity.
Replace Worn Mounts:
- If mounts are damaged, remove the bolts securing the mount to the frame and engine.
- Install new mounts and torque bolts to manufacturer specifications (typically around 30-50 ft-lbs).
- Reinstall the engine cover.

3. Repairing Suspension Components

Lift Vehicle:
- Use a jack to lift the vehicle and secure with jack stands.
Inspect and Replace Worn Parts:
- Check shocks, struts, and bushings for signs of wear.
- Remove any damaged components using a socket set.
- Install new components and torque to specifications.
Lower Vehicle:
- Carefully remove jack stands and lower the vehicle.

4. Addressing Drivetrain Issues

Inspect CV Joints and Driveshaft:
- Check for torn boots or excessive play in CV joints.
- Replace any damaged CV joints or driveshaft components following manufacturer guidelines.
Check Differential Fluid:
- Inspect fluid level and condition; replace if necessary according to service intervals.
