Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect and Replace CV Joints

Lift the Vehicle: Use a jack and secure it with jack stands to access the undercarriage.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect CV Joints: Look for any tears in the CV boot or signs of grease leaking.
- If damaged, proceed to replace the CV joint.
Remove the CV Joint: Use a pry bar to separate the CV joint from the transmission and remove any retaining clips.
Install New CV Joint: Apply grease as specified by the manufacturer, slide the new joint into place, and secure it with retaining clips.

3. Check and Replace Engine/Transmission Mounts

Inspect Mounts: Visually check engine and transmission mounts for cracks or separation.
Remove Old Mounts: Use a socket set to unbolt the mounts from the frame and the engine/transmission.
Install New Mounts: Position new mounts and tighten bolts to the manufacturer's specified torque.
Recheck Alignment: Ensure that the engine and transmission are properly aligned.

4. Examine Suspension Components

Inspect Bushings and Control Arms: Look for any signs of wear or damage.
Replace Worn Components: If bushings are cracked, remove the control arm using a socket set and replace the bushings.
Reassemble and Torque: Reinstall the control arm and torque all bolts to specifications.
