Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on the vehicle.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check fluid level.
If low, top off with the correct type of ATF (Automatic Transmission Fluid) as specified in the owner’s manual.
Inspect for burnt smell or dark color indicating the need for a fluid change.

3. Inspect and Replace Motor/Transmission Mounts

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the mounts for any cracks or excessive wear.
If necessary, remove the bolts securing the damaged mount using a socket set.
Replace with a new mount following the manufacturer’s specifications for torque values.
Reinstall the bolts and lower the vehicle.

4. Check Driveshaft and CV Joints

Inspect the driveshaft for any signs of damage, such as dents or excessive rust.
Check the CV joints for any torn boots or grease leakage.
If damaged, remove the driveshaft by taking out the retaining bolts and replace it with a new one.
Reinstall and torque to manufacturer specifications.
