Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems; ensure the vehicle is on a flat surface and securely raised when needed.

2. Inspect and Replace Engine/Transmission Mounts

Visual Inspection: Check for cracks, tears, or excessive movement in the engine and transmission mounts.
Remove Old Mounts:
- Use a socket set to remove the bolts securing the mounts.
- Carefully support the engine or transmission with a jack if necessary.
Install New Mounts:
- Position the new mounts and hand-tighten the bolts.
- Use a torque wrench to tighten to the manufacturer's specifications (refer to the service manual for torque values).

3. Inspect and Replace Drive Shafts/CV Joints

Remove Drive Shafts:
- Lift the vehicle and remove the wheels.
- Disconnect the drive shaft from the transmission and hub assembly.
Inspect CV Joints: Check for torn boots or excessive play.
Install New Drive Shafts/CV Joints:
- Position the new drive shaft and secure it back to the transmission and hub assembly.
- Ensure all bolts are torqued to specifications.

4. Change Transmission Fluid

Drain Old Fluid: Remove the transmission drain plug and allow fluid to drain completely.
Replace Filter: If applicable, remove the transmission filter and replace it with a new one.
Refill with New Fluid: Use the manufacturer's recommended transmission fluid and refill through the dipstick tube or designated fill port.
