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.
