the only real cure is a new gearbox, but at high mileage, thick oil helps
a lot to keep it quite, albeit at a slight power loss.

All I can say is try a well worn transfer box, main box, and 2 diffs in an
uninsulated series 3 landrover equpped with off road tyres at 70mph for
REAL noise :-)

I had a 2nd hand Maestro with a gearbox that was stiff as hell to start
with then became excessively loose and a tad noisy after 15 mins driving.

Drained the oil hot and it fell out (literally) like water. Half an hour
in a big jar outside in January and you could turn the jar upside down and
nothing came out.

I replaced it with (I forget the exact brand) a synthetic gearoil with a
low viscosity/temperature variation, and it was impressively improved. The
gearbox had suffered over the years, but it worked perfectly well for
several years afterwards until everything else fell off and I traded it in.

(I did flush the gearbox before refilling as the crap that came out was
full of allsorts).

I might be able to look up the oil if anyones interested, but it wasn't
excessively expensive, just you won't get it in Halfords.
