Yup.  Don't keep the throttle pinned as you hit the ground -- that's just
extra *** everything.  That, and it sounds like you didn't quite have
the gears adjusted right.

You want as little lash as possible, while still having some the whole way
around.

What I mean is this:

When adjusting your gear lash, rock your spur gear back and forth (so your
spur moves, but the pinion doesn't -- we're looking at the free-play of
the gear mesh) and see how much it moves.  Rotate the spur a bit and check
again.  You want to set your lash at the tightest point (no gears are
perfectly round) so that the spur gear rocks the smallest amount possible
and still have it rock a bit.  Then your gear lash is set as good as it
can be, and your truck will run as quiet as it can, and your gears will
last as long as they can too.

You should follow this whole procedure up by
turning the radio and car on and *testing* the gear lash for noise.
This is the only way I've been able to get it to be quiet.
If it's not quiet, try backing the gear lash off just the smallest
amount possible. Repeat until noise is gone, or change gears.
