HOW DO i GET INTO THE WASHING MC TO REFIT SUPPORT?

mY aQUARIUS 1200 WM34 leaks occassionally because it vibrates at times very badly. I have removed the top and the drum appears to be twisted. BUT i cannot get at anything because the sides are spot welded together. In the old days the back was held on by screws? Do I have to turn it upside down? The drum appears to be held with 2 steel suuports on a swivel bearing? I can easily reposition the drum in the centre by hand but it goes back to offset when I let go. Is there a spring support come off? Ron Sayle
