Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and is in "Park" or "Neutral."
Disconnect the negative battery terminal to prevent electrical shorts.
Gather all necessary tools and parts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, socket set, drain pan, funnel.
Remove the transmission fluid drain plug and allow the old fluid to completely drain into the pan.
Replace the drain plug and torque it to the manufacturer's specifications.
Using the transmission fluid pump, fill the transmission with new fluid until it reaches the correct level. Use the specified type of transmission fluid as per the owner's manual.

3. Inspect and Replace Engine and Transmission Mounts

Tools Required: Jack and jack stands, socket set, torque wrench.
Raise the vehicle safely on jack stands.
Remove any components obstructing access to the engine and transmission mounts.
Inspect the mounts for cracks or excessive wear. If damaged, unbolt the old mounts and replace them with new ones.
Tighten the new mounts to the manufacturer’s torque specifications.

4. Inspect Drive Shafts and CV Joints

Tools Required: Socket set, pry bar.
Remove the wheels to gain access to the drive shafts.
Inspect the CV joints for any signs of damage, such as torn boots or excessive play.
If any damage is found, replace the CV joint or drive shaft as necessary.
