This squeaking has been driving me nuts for a year now too. I just received
all the goodies from Bus Depot necessary to replace all the front end
bushings, ball joints, etc.
My plan is to replace both upper and lower bushings, ball joints, and do a
complete brake job, including new rotors, caliper rebuild, pads, and wheel
bearings.
Cost for all the parts (Syncro): ~$500.00
Let me know if you want part numbers

Don't overlook the balljoint itself as the source of the squeak, especially
if the boot is, or has been, torn/cracked. I've seen quite a few balljoints
squeak/creak in my 20 years of Vw repair. The best way to rid the squeak for
good, is to replace the balljoint AND the bushings at the same time (unless
of course the bushings were done recently and correctly). Still less than
the junkyard arm at $75 or so.
