IIRC, not sure, that it said that in my 2008 Mustang's shop manual. I
think that car had the usual iron (steel?) differential housing, but the
tubes to the rear wheels were steel tubes pressed into the pumpkin. I
can see how that could be problematic--esp. if the weight of the wheels,
brakes, etc. was suspended--but I did it several times and the car was
fine when I traded it in at about 124K miles, with the original clutch
and brakes. Healey rear axles, I think, are solid iron so probably not
an issue with them.

IIRC, not sure, that it said that in my 2008 Mustang's shop manual.
I think that car had the usual iron (steel?) differential housing,
but the tubes to the rear wheels were steel tubes pressed into the
pumpkin. I can see how that could be problematic--esp. if the weight
of the wheels, brakes, etc. was suspended--but I did it several
times and the car was fine when I traded it in at about 124K miles,
with the original clutch and brakes. Healey rear axles, I think, are
solid iron so probably not an issue with them.<br>

Modern 'unibody' cars have specific jacking points, and I
suspect putting lifts elsewhere <i>could </i>deform the
under-body panels. I recently did a wheel alignment on my
BN2, and using the QJ was indispensable, essentially
trial-and-error: lots of lift, set, check, drive, lift, set
check, drive ... <br>

I have a grease pit for jobs 'on wheels.' I almost filled it
in after my dad died--I'm sure it would be illegal these
days--but it's just <i>SO</i> useful, but I spent a
half-day building new covers for it.<br>

ps. I read somewhere that jacking the pumpkin on live axle
cars was a not good idea, though I've done it for years and
not had any issues that I know of. I suspect it could bend
the tubes going to the wheels.<br>
