  7. While keeping the installation surfaces of the rear differential and power plant frame parallel, loosen the stud bolt shown in Step 6 and remove it with the power plant frame.
    CAUTION:
    • If the power plant frame tilts from the rear differential, the threaded hole of the rear differential may be damaged. When removing the power plant frame, loosen the stud bolt while keeping the installation surfaces of the rear differential and power plant frame parallel.
    NOTE:
    • The stud bolt is pressed in the power plant frame, therefore, it requires greater torque than a general bolt when loosening.
