Rear suspension on an 86 100CS

[Rodger Donaldson]

I'm a recent Audi convert, having aquired a cheap (1100 pound) Audi 100CS
Quattro Avant to hack around England while I'm contracting here.  It's a
superb car - handles like a smaller, sportier car, surprisingly frugal with
the fuel, loads of power (being a 2.2), quiet, and civilised.  Basically,
it's a brilliant car.

However, a rather annoying problem has reared its head: the left rear
suspension has developed a persistant, squirrelly squeaking whenever the car
moves.  From poking around the audifans archives, I'm guessing that this is
most likely a problem with the bushes.

Having had a poke around under the car, it seems that most of the noise is
coming from the point where the suspension attaches to the chassis under the
rear of the passenger door; I have (obviously) a few questions:

1/ What will the bushes look like if worn?  They don't appear to have
disintegrated, so I'm only assuming they're the problem.

2/ Is it, as I assume, a problem that should be fixed sooner rather than
later, lest bad things happen?

3/ How awkward/dangerous is it to monkey with the likely culprit; or to put
it another way: I don't have a lot of experience poking at automotive
mechanics, and I don't have a huge range of tools available.  Would it be
safe/sensible/easy to block the rear of the car up, unbolt the problem area,
replace the bush, bolt it on again, and drive off into the sunset?  Or
should I get a real mechanic to do the job?
