Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine and transmission mounts; typically found near the front and rear of the engine and on the transmission.
3. Visually inspect the mounts for cracks, tears, or signs of wear.
4. If damaged, remove the bolts securing the mounts using a socket set.
5. Replace with new mounts, ensuring proper alignment, and torque bolts to manufacturer specifications (usually around 35-45 ft-lbs).

3. Inspect and Replace CV Axles if Necessary

Sub-steps:
1. Remove the wheel and tire assemblies to access the CV axles.
2. Check for any play in the CV joints by manually moving them.
3. If worn, remove the axle nut with a socket and impact wrench.
4. Disconnect the CV joint from the hub and remove the axle from the transmission.
5. Install the new CV axle, ensuring it is seated properly, and reattach the hub.
6. Replace the axle nut and torque to manufacturer specifications (usually around 100 ft-lbs).
