Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely elevated using jack stands.
Disconnect the battery to prevent any electrical issues.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check fluid level.
If fluid is low, add the manufacturer-recommended transmission fluid type.

3. Inspect and Replace Engine/Transmission Mounts

Locate and visually inspect the engine and transmission mounts for cracks or separation.
If damaged, use a socket set to remove the bolts securing the mounts.
Install new mounts by positioning them correctly and torquing to manufacturer specifications.

4. Examine the Driveshaft and CV Joints

Inspect the driveshaft for any signs of damage or imbalance.
Check CV joints for torn boots or excessive play.
If any parts are damaged, remove the faulty components using a socket set and replace them with new ones.

5. Final Assembly and Fluid Check

Reinstall any components that were removed during inspection.
Recheck transmission fluid level and add fluid as necessary.
Reconnect the battery.
