plain and simple regardless of who did what in days of old... decide for yo=
urself what makes sense.....spinning the driveshaft without the gears spinn=
ing is rotating the shaft inside the gears at a speed equal to the road whe=
el rotation speed divided by you rear end ratios IE: the turns per mile on =
your speedo face, revolutions every minute at 60 mph.
So example....after 500 miles ~ 8 hrs @ 60mph w/ 3.90 rear roughly 1000revs=
per mile =3D 1/2 million revolutions of the shaft with no lube! Your mains=
haft sits above the oil level in your tranny. The laygear (cluster gear) si=
ts partially submerged. The oil slung all over the place by the laygear is =
what drips down and lubes the bushes/shaft via spiral grooves in the bushes=
(not all...some are only drilled weep holes)
I'd be had pressed to believe you are not prematurely wearing away the bush=
es and edges of the gears.=C2=A0 When driven by the engine, the input shaft=
is always spinning the cluster gear, car moving or not. So oil is being sl=
oshed everywhere.
20-30 miles at under 45-50mph across town..maybe ...but highway no way!. Bu=
t I also reference an instance I know of where a Jeep had jostled into gear=
while being towed.... and was only found so at the trip destination. You c=
ould only shift between reverse and neutral....and the vehicle could not be=
moved under it's own power (not a 4WD either so same drive scenario ) The =
engine suffered as well.

I've seen several MGBs (different gearbox design?) and MX5s being flat towe=

Just wondering.
