Stabilizer Bar Mounts

[GREG CIRILLO <GCIRILLO@gkmg.com>]

I've been told by an Audi dealer that my rear stabilizer bar mounts (1991,
90Q, 20V) require service of an unspecified nature.  When the back of
the car becomes unloaded (braking at low speeds or just lifting up at the
rear wheel well when stationary), there is a heavy metallic "doink"  (Just a
thought: We should generate a list of car sounds at an ftp site so we can
refer to them!).   

It's clearly a rear suspension problem.  Has anyone experienced this?  If
so, what is the cause, and could a reasonably handy person -me- fix it with
standard tools?
