mately 25 MPH is attained, turn ignition switch on and move control
lever to either DR position.

universal joint and remove from the car by sliding the front universal
joint and shaft assembly backwards, or raise the rear wheels off the
ground to prevent possible damage to the transmission.
When towing the car with the propeller shaft disconnected, the tow
car operator should be cautioned to make certain that oil does not
leak from the rear bearing retainer.
