My 1981 Holdsworth Villa Conversion had a similar problem on the R/H
front wheel - a rhythmic squeak squeak squeak that got faster as the van
got faster. It was so loud that people would turn to see what the noise
was. Raised the front wheel and the squeak disappeared. Lowered the
wheel and the squeak returned. After a lot of thought, I pulled over and
quickly removed the front wheel trim. The squeak stopped. Turned out to
be the tyre (tire)  flexing onto the rim of cheap plastic wheel trim.
Some silicon lubricant spray cured the squeak. Must get some proper
metal VW hub caps if the squeak returns.

Rick, I would go to a large tyre fitter (in the UK we have drive in tyre
garages like Quik Fit) and ask them if the know what the problem is -
(sounds like a rubber bush on the anti roll bar has worn and you are
getting metal on metal you can see a good photograph

Don't get it fixed there unless the price is right. Get a second quote
from a VW specialist.
