Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, jack stands, floor jack.
Instructions:
1. Raise the vehicle using a floor jack and secure it with jack stands.
2. Locate the engine mounts (typically found at the front and rear of the engine).
3. Inspect each mount for cracks, tears, or signs of fluid leakage.
4. If damaged, remove the bolts securing the mount to the engine and the chassis.
5. Install the new engine mount and torque bolts to manufacturer's specifications (typically around 50-60 ft-lbs).

3. Inspect and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, torque wrench.
Instructions:
1. Remove the transmission fluid dipstick and check the fluid's color and level.
2. If the fluid is dark or burnt, drain the old fluid using a pump.
3. Replace with the manufacturer's recommended transmission fluid (typically Toyota ATF WS).
4. Refill the transmission to the proper level and recheck with the dipstick.
5. Ensure to torque the transmission pan bolts (if removed) to specifications.

4. Check and Replace CV Joints or Drive Shafts

Tools Required: Socket set, pry bar, torque wrench.
Instructions:
1. Inspect the CV joints for torn boots or excessive play by moving the joint back and forth.
2. If damaged, remove the axle nut and slide the CV axle out of the hub.
3. Replace with a new CV axle or joint and ensure proper alignment.
4. Reattach the axle nut and torque to specifications (typically around 150 ft-lbs).
