On an 82 suburban, I have a two piece driveshaft with the 3 u joints ,and
there's a bearing with the bonded rubber is peeled almost all the way
around. its shot. Its not a ujoint or cardan, its just a roller bearing
bonded in a sheetmetal pillow block housing. and a water shield on it. The
Chilton's and the Haynes don't say how critical the alignment is . however I
can look down the shaft and see the front and rear shafts are not aligned
straight. side to side. I guess I,m concerned about the splines where the
two shafts slip together and if mis alignment will wear them out. Should I
try and make the shafts straight from the tranny to the rear end, and align
the bearing with the shafts, or leave the bearing loose and tighten the u
joints and tighten the bearing where it wants to stay put at.

that's called a hanger bearing and it's not deathly critical but you
should keep it as straight as possible...but change it first.

It's a carrier bearing. Just replace it.

If it's bad, replace it.
Hanger, Carrier, or Center Support bearing are all terminologies used
to
describe the part.

as to yer concern for tightening....................

tighten the u-joints first, then tighten the Center Support bearing
where it
wants to set at. Give it a few jostles to insure it's not in some
weird bind.
