Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, jack and jack stands, replacement mounts (if needed).
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Engine and Transmission Mounts

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Visually inspect the engine and transmission mounts for cracks or separation.
- If damaged, remove the bolts securing the mounts using a socket set.
- Replace with new mounts, ensuring they are aligned properly.
- Torque the mount bolts to the manufacturer’s specifications (typically found in the service manual).

3. Inspect Driveshaft and CV Joints

Sub-steps:
- Remove the wheels (if necessary) and inspect the CV joints for any tears or leaks in the rubber boot.
- Check for any wobbling or play in the driveshaft.
- If any components are damaged, replace the driveshaft or CV joints as needed.
- Reassemble any removed components, ensuring proper torque specifications are followed.

4. Transmission Fluid Check and Replacement

Sub-steps:
- Locate the transmission dipstick; check the fluid level and condition.
- If low or discolored, drain the old fluid using a fluid pump, and replace with OEM-spec transmission fluid.
- Recheck fluid level after replacement and ensure it is within the acceptable range.
