Solution

1. Preparation

Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical shorts during repair.

2. Inspect and Replace Transmission Mounts

Locate the Transmission Mounts:
- Raise the vehicle on jack stands and secure it.
- Remove any protective underbody covers if necessary to access the mounts.
Remove Old Transmission Mounts:
- Using a socket set, remove the bolts securing the transmission mounts to the transmission and the chassis.
- Carefully support the transmission with a jack or transmission stand as needed.
Install New Transmission Mounts:
- Position the new mounts in place.
- Torque the bolts to the manufacturer’s specifications (typically around 30-40 Nm; refer to service manual for exact values).

3. Inspect and Replace Motor Mounts

Locate Motor Mounts:
- Inspect the engine mounts visually for signs of wear or cracking.
Remove Old Motor Mounts:
- Remove the bolts securing the engine mounts to the engine and the subframe using a socket set.
- Carefully lift the engine slightly with a jack to relieve pressure on the mounts.
Install New Motor Mounts:
- Position the new mounts and secure them with the bolts.
- Torque to the manufacturer’s specifications.

4. Inspect and Replace Drive Shafts or CV Joints if Necessary

Visual Inspection:
- Look for any visible damage on the drive shafts and CV joints.
Remove Drive Shaft:
- If any damage is found, use a socket set to remove the bolts securing the drive shaft to the transmission and wheel hub.
- Carefully slide the drive shaft out.
Install New Drive Shaft:
- Position the new drive shaft, ensuring proper alignment.
- Secure it with the bolts and torque them to the specified values.
