Over the past few months I have noticed a vibration under heavy(ish)
acceration or load in my Syncro Double Cab.  The noise seems to be coming
from somewhere below me when I am going up a steep hill where I have to
gear down in to third to maintain any sort of speed.  If I ease off of the
accerator the noise goes away.  This same vibration also occurs when I
accerate quickly from a stop in all gears.  It is always the same RPM range
that it occurs.  I assume somewhere between 2000 and 3500 (no tach I can't
tell exactly).

I put castrol 70w90 synthetic gear oil in both the front and rear boxes
this helped shifting but there is still the same vibration (still a little
occasional grinding in 1st to 2nd).  Other things that I checked were tire
pressure and ballance and loose trim pieces.... still no luck  :(

Any idea what the problem is?

Thanks in advance!
