So I have a problem, while driving today out of nowhere both my rear wheels locked up. I could move forward 2 feet and drive in reverse 2 feet before they locked up but they were locked, all gears worked fine including reverse.

I was finally able to drive in reverse without the rear wheels locking up so i parked the car, when I tried to go forward they locked up then reverse worked fine, then I went forward and now I can drive the car with no locking of the rear wheels but i am afraid to drive the car. I also want to note that when they locked up i could put the trans in neutral and the rear wheels would still lock up - this leads me to believe that the trans is fine

Do you guys have any ideas as to what this could be?

thanks

car is 1983 Porsche 944 na
