Tools required: Socket set, torque wrench.
Locate the transmission mounts; usually found on the engine and transmission.
Remove the bolts securing the mounts using a socket set.
Replace with new mounts and torque bolts to manufacturer specifications.

4. Check and Replace Driveshaft or CV Joints

Tools required: Jack and jack stands, socket set, grease.
Lift the vehicle and secure it with jack stands.
Inspect the driveshaft for play; if damaged, replace it.
For CV joints, look for torn boots; if found, replace the joint.
Apply grease to new components as specified.

5. Reassemble and Test

Reassemble any components removed during inspection.
Reconnect the battery.
Start the vehicle and check for normal operation and absence of clunking noise.
