Step 2: Use a socket set to remove the bolts securing the mounts.
Step 3: Remove the old mounts and inspect for cracks or wear.
Step 4: Install new engine and transmission mounts, tightening bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Tools Required: Socket set, torque wrench.

3. Check and Replace Transmission Fluid

Step 1: Locate the transmission dipstick or fill plug.
Step 2: Extract old transmission fluid using a fluid pump or by draining from the pan.
Step 3: Replace with manufacturer-recommended transmission fluid (e.g., VW G 052 162 A2).
Step 4: Recheck fluid levels after running the engine for a few minutes and add as necessary.
Tools Required: Fluid pump, torque wrench.

4. Inspect Drive Shaft and CV Joints

Step 1: Elevate the vehicle securely on jack stands.
Step 2: Inspect the drive shaft for any bends, cracks, or damage.
Step 3: Check CV joints for torn boots or excessive play.
Step 4: Replace any damaged components with OEM parts as needed.
