[Healeys] OT: Axle Jacking

[Bob Spidell]

It's a Catch 22; if I jack the rear first, I can't get the jack under the front crossmember, if I jack the front first the only way to jack the rear is to get under the diff from the passenger (non-exhaust) side (on an LHD car). 

I usually get the car up four jackstands to do work under the car.

I just use a piece of wood that fits across the rear crossmember. I've never jacked using the diff.

This is really surprising to me. I have always lifted cars by putting a floor jack under the differential, and I have never had a problem nor have I heard of any problem with the practice. I suppose it could be something specific to Mustangs, but all you have to do is lift a Healey axle housing (even without the differential) to realize that it's pretty solid. I can't believe this is a common problem for all cars, and definitely not for a Healey. 

I CAN see that putting all the pressure on the drain plug at the bottom of the differential housing could be a problem. 

But, of course, now I'll worry about this the next time I jack up my Healey. Thanks Bob... :)

Thought about posting this to shop-talk, but I suspect there's more general car knowledge here. 

I believe my Mustang manual has admonitions against jacking the rear by placing a floor jack under the rear pumpkin. I've jacked-up Healeys this way for years, but the Healey axle housing is a single chunk of iron; the Mustang probably has thin-wall tubes from the pumpkin to the wheels. Theoretically, you could bend the thin-wall tubes, but I've done it a few times with no noticeable issues. 

Thoughts from the Illuminati?
