Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical issues during repairs.
Ensure the vehicle is on a level surface and securely raised on jack stands if necessary.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove the bolts securing the engine mount to the engine block and chassis.
Use a pry bar to gently lift the engine to relieve pressure on the mount.
Remove the old mount and install the new mount, tightening bolts to the manufacturer’s specifications.
Reconnect the negative battery terminal.

3. Check and Replace Transmission Fluid

Tools Required: Fluid pump, socket set, transmission fluid (specific to Toyota)
Remove the transmission fluid pan (if applicable) and check for metal shavings or debris.
Replace the transmission filter if applicable, and clean the pan before reinstalling.
Refill the transmission with the appropriate fluid type until it reaches the correct level.

4. Inspect and Replace Driveshaft or CV Joints

Tools Required: Socket set, jack stands
Remove the wheels and inspect the CV joints for cracks or tears.
If damaged, remove the CV joint by loosening the axle nut and sliding the axle out of the hub.
Replace with new CV joints or driveshaft as needed, ensuring all fasteners are torqued to specifications.
