shaking in reverse..at low revs???
 

hi all..anyone got any ideas on this or had anything like it???

got a 1995 n/a auto supra now...and when i put it in reverse and go back slowly it shakes as if the brakes are stuck...
if i go back at speed it seems ok ??...going in forward drive gears is fine just reverse. also a little bit shaky in netural when u rev it?
had all the brakes etc looked at and they are all fine..been told it might b to do with the propshaft... u joints ...or the diff ??

anyone got any ideas???

cheers
