Hi, I just Inherited a 1980 300TD Wagon

The Cars been parked since 2007, I've drained the oil and coolant, put some fresh diesel in and the car fires right up, But When I go to move it only the Drivers Rear Wheel is Moving, The Passenger Rear Will Move about 4 inches Forward or backward and then lock (like if the car were in park) The Car Drove beautiful prior to being parked in 2007 and I'm very eager to get it back on the road again. The Car Shifts Fine Into D or R and I'm not hearing any odd noises.

Thanks


Forrest
