   NOTE: Installation of the wood block prior to removing the upper engine torque axis mount allows the mount to be easily installed without lifting or jacking the powertrain.
2. Remove the three engine, upper engine torque axis mount-to-front cover nuts and the two engine mount-to-midrail bracket nuts, allowing the powertrain to rest on the block of wood.
