Jacking up under rear differential?

You get points for using 2 stands and lose them for how you did it.
In the late 70's we would use empty 55 gallon drums as stands to support the rear of F600 oil trucks while we rebuilt the springs and rear brakes because the shop didn't have any high stands until I took over in 82 and bought some. Nobody died, I guess we won.

Subtract another 1000 points. They’re Pittsburgh from Harbor Freight.

Do dead guys still have points?

I’m pretty sure they’re not holding any weight... they’re just kinda balanced/ stuck under the frame.

If they were full of liquid (water or oil) I could see that being somewhat safe, essentially a hydraulic jackstand, but empty? guess you got lucky there, must have been good drums.

I mean, its an 8.8. I doubt that supporting the rear of the truck would break the diff. It must be just the simple fact that it could theoretically tilt one way or another. It is not as stable as a 2 post lift.

only if they can tell the tale.

Wow, No one commented. I only wrote three words on that last one…

That "bible's" only use is to keep people from sueing the manufacturer when the truck falls on them...

I'm with Dirtman on this one. There are many things from the manufacturer provided information that you shouldn't ignore or at least take into consideration. Jacking up the back of the truck from the a steel or cast iron differential isn't one of them as long as you take the precaution not to damage the cover. Working under a vehicle supported in such a way is a Darwin Award winner waiting to happen.

Also note, they are talking about replacing a tire. One would hardly need to jack up the entire rear end to change one tire.
