Volks,

My 1991 GL has passed the 180,000 mile mark and it is getting VERY
noisy when it hits a bump (lots of bumps on Midwest streets).  The
mechanic I usually go to is very good, but not a VW specialist and is
not able to diagnose without a lot of expensive dismantling.  Every
van I've had got noisy when it reached this kind of mileage, and I
suspect that a good shop with Vanagon experience would be able to
tell me most of what I need to know,  just by driving it around and
hearing what I'm hearing.

Suggestions, anyone?

Thanks in advance

Steve
