Concerning the noise you may hear from the front end.
Before you go through the headache and expense of checking bearings etc,
take a look at the tires on the front, have they been rotated off the back?
Are they cupped?
At one point in time I had a very badly cupped set of tires on tha back end
of my 93 and a passenger sitting in the rear swore up and down that I had a
bad bearing in the rear end.
Replacing the tires corrected the "bad bearing" that this guy was willing to
bet money on.
I mention this as some combination of tires, EVs and driving habits seem to
contribute to cupping the tires and creating noises that sound just like a
bad bearing.
3. I know that everyone else has been driving their EVs for a long time
and are now de-sensitized, but should the front end be as noisy as it
is at highway speeds? Sounds almost like an unbalanced wheel or a shot
bearing, compared to my quiet (but slow) Vanagon.
