[Mgs] Bonus noise lossage

[mgbob at juno.com]

  How satisfying!  Axle work seems much simpler, and is done in a day.
  Noise certainly seems to come from different places.  Just a couple of weeks
ago, at one of our tech sessions, one of the guys noticed that, when the
wrench on crankshaft bolt was turned, the click of the ratchet could be felt
in the shift lever.
  We were re-timing a camshaft. Owner said the MGB was not perky. Cam was off
spec by one tooth.

So here's a lesson I've learned. When you think your gearbox is making a
terrible amount of noise, make sure it's not the axle.

Last year, I had a lot of sound vibrating right up into the shifter, which
would "go away" if I rested my hand upon said shifter. I figured a gearbox
overhaul was in my future.

But I also had the previously mentioned diff clunk, so I fixed that first.
I've since noticed two distinct classes of noisy driving:
 * at speeds below about 40, the dominant sound is engine and exhaust notes
(also known as "wheee!")
 * at speeds above about 40, the dominant sound becomes the wind rushing past
(also know as "faster!")

I think my gearbox might be just fine. Fortunately, I got the order of fixes
right.

I didn't realize how bad it wa; this year's spring re-introduction to driving
the MG has been one of the best I've enjoyed in years.
