TOB? DS too tight?.. help! (5spd swap probs)

[NemeGuero]

I get a skreetching noise, like a loose belt but louder coming from near the bellhousing I would assume. The noise only happens when I deccelerate and clutch play doesn't affect it, neither does what gear I'm in including neutral. It won't do it however when I'm at a complete stop. And the noise goes away when I depress the break pedal. Could this be a bad throw out bearing? why would it then not do it at idle or stop when I depress the clutch?

also, slowing down at low rpms.. my car shakes violently like it's going to stall... doesn't stall but just stops shaking. I think this is a driveshaft problem.

R240NA, was that DS non-abs? if not, that may be my problem and I'll have to switch the rear section. I had to bolt it to the diff first and then bolt up the mid section, but it seemed like it was under pressure still.

help please
