Where to place jackstands 123
So I just had the 300CD on jackstands for a while and did a bunch of work... but I was never really happy with where I had placed them. I couldn't put them under the factory jack points, my jack was in the way, and there is that dang seam that is in the way. And I didn't want to damage the car. What the heck do guys who have rusted out jack points do? If I'm gonna have her up on stands again to change in my new Vogtland springs, I don't want to be afraid of pulling her off the stands and squishing myself.
If folks could post any good pix they have of good safe places they have used jack stands I would appreciate them.

In front, I put the stands in the pocket where the control arms meet the subframe. in the rear I just set them on the subframe.

Granted, I have a w124, but I always jack by the main crossbeam, that runs between the engine and transmisison, and put the jackstands under the jack points. I never lift up just one side of the car, even if I will only be working on one side. I always lift up either the entire front, or entire rear, of the car. I've heard that is the safest way to do it.

For jacking the front: I see what you mean about the main crossbeam, I like that a lot (I hadn't realized it was solid enough to lift the whole car) and then jackstands on either side at the jackpoints. For jacking the back: how do you get the whole back end in the air? Do you work back and forth from one side to the other till you get it all the way up? Thanx

under the diff?
Well I guess that would work. It's a long way up there, I'm not sure my floor jack can get it very high since it will already be reaching up so far. Maybe some thick wooden blocks. Have you jacked on the diff? It didn't deform the car floor where it is attached and push the diff up into the car?

Oh, yes, I have jacked the cars up this way for decades. the dif is very strongly supported, no chance of damaging it or the floorpan. MB recommends this method to lift the rear.

I've been doing this also, the place for the jack stands are under lift points. Or if you're feeling up to it, under the trailing arms, but the car has to be pretty high up. I do use a piece of wood on the floor jack. It is a long way, so I have to use very small pumps on the handle for a little while. My three ton floor jack weighs just about that, so how much can it lift?

I use the factory jack and then put jack stands under the jack points. Since the factory jack stands off to one side of the car, it doesn't get in the way of the jack stands. Jacking under the differential also sounds like a good idea, which I will have to try next time. I'll probably have to use a block of wood between my floor jack and the differential to get enough height.

where not to place 'em

I appreciate all this advice. I am not one of those alarmist types, but just the same a guy can kill himself by not paying attention to where he places the jack/jackstands. (and not a good way to go either) Along with the usual number of folks on this forum jacking up cars there will soon be over 3 dozen extra members trying to install their/our new Vogtland springs in our 123s, I hope we are all careful and successful!
