[200q20v] Powersteering may be going!

[Joseph Vanzeipel]

For the past few weeks I have heard what can only be described as a clicking
noise from the belts or pumps.  I thought not much of it and thought it was
a misaligned belt.  Well, the other day, parallel parking was an exercise in
arm strength (and only driving cars with power steering, it was quite an
exercise).  This got my attention.  The clicking sound turns out not to be
the belts, as they are all in alignment, but (from what I think) is the
bearing in the power steering pump (the top driver side, I believe).  I have
only driven the car on weekends and a few weekdays since three weeks ago
(after a good 400 mile trip).

Here's my questions:  Is there a way to just replace the bearing without
replacing the entire pump?  Is there another test to make sure it really is
the power steering pump and not something else?  How much will I be looking
at for a pump?  For labor? (I can't work on it myself for the meantime, I
just started college, and don't really have the time or the patience).

TIA,
