Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery to avoid any electrical issues during repair.

2. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Remove the battery negative terminal.
2. Raise the vehicle and secure it with jack stands.
3. Locate the engine and transmission mounts.
4. Visually inspect for cracks or excessive wear.
5. Remove the bolts securing the mounts using a socket set.
6. Replace with new mounts, ensuring proper alignment.
7. Torque the mounting bolts to the manufacturer's specifications (typically around 50-70 ft-lbs).
8. Reconnect the battery terminal.

3. Inspect and Replace CV Joints/Axles

Sub-steps:
1. Remove the front wheels using a tire iron.
2. Inspect CV joints for any signs of tearing or grease leakage.
3. If damaged, remove the axle nuts and detach the axle from the hub.
4. Remove the retaining clips and slide the axle out of the transmission.
5. Install the new axle by reversing the removal steps, ensuring the retaining clips are securely in place.
6. Torque the axle nut to the manufacturer's specification (typically around 150-175 ft-lbs).

4. Examine and Replace Suspension Components

Sub-steps:
1. Inspect struts and shocks for leaks or physical damage.
2. If damage is found, remove the strut assembly by unbolting it from the knuckle and top mounts.
3. Replace the strut or shock and reassemble in reverse order.
4. Ensure all bolts are torqued to specifications (typically around 25-35 ft-lbs for upper mounts).
5. Reinstall the wheels and lower the vehicle.
