Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, jack and jack stands, fluid catch pan.
Allow the engine to cool before starting any work.
Disconnect the battery to avoid any electrical issues during repairs.

2. Engine Mount Inspection

Sub-steps:
1. Lift the vehicle securely using a jack and jack stands.
2. Visually inspect the engine mounts for cracks, tears, or excessive movement.
3. If damaged, remove the bolts securing the mounts using a socket set.
4. Replace with new engine mounts, ensuring they are torqued to the manufacturer’s specifications (typically around 40-50 ft-lbs).

3. Transmission Fluid Check

Sub-steps:
1. Locate the transmission dipstick (if equipped) and remove it.
2. Inspect the fluid level; add fluid if low, using the correct type (typically Toyota ATF WS).
3. If fluid is discolored or has a burnt smell, perform a fluid change:
  - Remove the transmission pan and replace the filter.
  - Reinstall the pan with a new gasket and torque bolts to specification.

4. Throttle Body Cleaning

Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Use throttle body cleaner and a soft cloth to remove carbon deposits from the throttle body.
3. Reinstall the air intake duct securely.

5. CV Joint Inspection

Sub-steps:
1. Visually inspect the CV joints for any tears in the boots or grease leakage.
2. If damaged, remove the axle from the hub and transmission using a socket set.
3. Replace with a new axle assembly, ensuring proper fit and torque specifications.
