Solution

1. Preparation

Tools Required: Safety glasses, gloves, jack stands, wheel chocks.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Transmission Fluid

Check the transmission fluid level; if low, add the recommended fluid type (consult the owner's manual).
If the fluid is dark or burned, drain and replace it:
1. Locate the transmission drain plug and remove it using a socket set.
2. Allow the fluid to drain completely into a suitable container.
3. Replace the drain plug and torque to manufacturer's specifications.
4. Refill the transmission with the correct type and amount of fluid.

3. Inspect and Replace Mounts

Tools Required: Socket set, torque wrench.
If mounts are damaged:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine and transmission mounts.
3. Remove the bolts securing the mounts using a socket set.
4. Replace with new mounts and tighten bolts to manufacturer's torque specifications.

4. Inspect CV Joints and Driveshaft

Tools Required: Pliers, socket set.
To replace damaged CV joints:
1. Lift the vehicle and remove the wheel.
2. Remove the axle nut and disconnect the CV joint from the wheel hub.
3. Slide the CV joint off the driveshaft and inspect for damage.
4. Replace with a new CV joint and reassemble in reverse order.
