[s-cars] drive shaft, knocking or vibration?

Speaking of knocking and vibrations,

I had a sound along the drive shaft also, but mine only happened under load
and/or sharp uphill to the left turns. Turns out mine was the exhaust
hitting the cross-member(or whatever it's called). I loosened the bolts that
connect the mid and rear section of the exhaust(4 bolts 17 mm, I believe).
Once loose(plenty of penetrating oil) I jacked up the rear muffler at the
front passenger side hanger and re-tightened the 4 bolts. The rubber hanger
where I jacked up the muffler was so worn and stretched, I had a inch gap.
So new hanger and 2 weeks later, no more rattling noises.

Now that's fixed other noises have come out of the woodwork or just more
noticable now.

If I knew how easy of a fix it was I wouldn't have neglected it for so long.
Goes to show if you have a loud stereo system ("noise, what noise") you can
tolerate a lot ;-)
