I noticed this time that the cable drum on the left hand side (facing
the door from inside the garage) was touching the bracket and that was
causing the whole problem. I checked both cable drums and they were
rock solid.
It should be possible to unseat the drum set screws and move the drum
to a spot where it doesn't rub against anything. Or else use that
opportunity to remove a bit of material or bend the bracket just
enough not to be in the way of the pulley drum.
One more suggestion. Is it possible to file down the cable drum rim
so that it doesn't bind anymore? Of course make sure there is enough
rim left not to let the cable slip out.

No, I don't think that will solve my problem because the whole shaft
is moving to the right after a few days. Filing the drum will give me
another day before the problem recurs (if I read you right). Thanks
for everyone's thoughts... I guess I have to get the new door

jezzuus guys, there is a setscrew that holds the shaft to the center
bearing, or the end of the spring to the shaft or whatver that is
supposed to keep it in place. It is not meant to float- Hide quoted text -

I checked the bushings as Richard (above) suggested but I can't seem
to find anything wrong. I oiled the whole thing last to last
weekend. BUT, I can see that the torsion shaft can be moved to the
right if I try pulling on it from the right. So, I have confirmed my
diagnosis that due to the spring tension the torsion shaft does slip
to the right. I tried to remove the end bearing plates but I am
unable to get my LHS pulley off to get it completely off and put a new
one. I also checked on the net but wherever I went they don't have
end bearing plates like mine, maybe my door is really very old. They
are simply like a "D" lying on its back and hole to let the shaft
through and two holes to pin it to the contraption that is holding the
rails in place. It does not have the two sets of holes to allow R =
12" or R = 15" selection like the current end-bearing plates do.

Last but one weekend ago, I have re-installed the door taking care
that the rod is in its rightmost position (so that there is no
slippage after I wind the spring). I have used the door manually and
it works but as soon as I hook the GDO it starts making sounds that
make me feel uneasy... I have kept the usage to the minimum..

Can I post photos of my situation on this forum?
