Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on level ground and the engine is off.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, stethoscope, and wheel chocks.

2. Inspect and Replace Suspension Components

Remove the front wheels using a socket set.
Inspect the following components:
- Control arms and bushings: Check for cracks or separation. Replace if damaged.
- Strut assembly: Look for leaking struts or damaged mounts. Replace if necessary.
- Sway bar links: If worn, replace with new ones.
Sub-steps:
1. Remove the nuts/bolts fixing the control arms and sway bar links.
2. Use a pry bar to remove the old components.
3. Install new components, tightening to manufacturer specifications (typically around 50-70 ft-lbs for control arm bolts).

3. Check and Replace CV Joints

Inspect CV joints for signs of wear.
If damaged, follow these steps to replace:
1. Remove the wheel, then loosen and remove the axle nut.
2. Remove the lower control arm to access the CV joint.
3. Pull the axle out of the transmission.
4. Install the new CV joint by reversing the removal steps, ensuring proper seating and alignment.
5. Reinstall the axle nut to the appropriate torque specification (usually around 180 ft-lbs).

4. Inspect and Replace Engine/Transmission Mounts

Visually inspect mounts for cracks or excessive wear.
If replacements are needed:
1. Support the engine with a jack.
2. Remove the mounting bolts using a socket set.
3. Replace the old mounts with new ones, tightening to manufacturer specifications.
