Hi,

Here's my vanagon riddle for today:

What is it, that makes a vibration in my 84- appears at about 40 mph
on up, dissapears at 30 or below.  Makes a low rumbling sound that is
not rpm related, sounds like when the fan comes on, or driving on a
rough surface, but louder.  It's louder until it warms up on the
freeway, but get louder again around a corner, quieter on the
straights.  I just changed two tires, as I thought that was it.

Thanks in advance for your solution to this riddle,

Dan
