Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to prevent any electrical accidents.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove any components obstructing access to the engine mounts (if necessary).
Use a pry bar to lift the engine slightly and remove the bolts securing the engine mount.
Replace with new engine mounts and torque to manufacturer specifications (consult repair manual for torque values).
Reassemble any components that were removed.

3. Transmission Fluid Check and Change

Tools Required: Transmission fluid pump, fluid catch pan, socket set
Remove the transmission pan (if applicable) and inspect for metal shavings or debris.
Drain old transmission fluid into a catch pan.
Replace the transmission filter if applicable.
Refill with new transmission fluid (consult owner’s manual for the correct type and amount).
Reinstall the transmission pan and torque bolts to specifications.

4. Inspect and Replace Damaged Driveshaft or CV Joints

Tools Required: Jack and jack stands, socket set
Safely lift the vehicle and remove the wheels for better access.
Inspect the driveshaft for any visible damage or play in the CV joints.
If damaged, remove the driveshaft by unbolting it from the transmission and rear differential.
Replace with a new driveshaft or CV joints as necessary.
Reinstall and torque all bolts to specifications.
