Safe lifting points with a floor jack?

I know about the four lifting points on the side of the car. But I like to put my jack stands under those. Is it safe to lift a R230 from the cross member under the engine? There is a hard plastic bumber in the center that sticks out from the shield. I assume this was put there as a lifting point. Can somoene confirm? Is it safe to lift the rear of the car from the rear differential?

Can anyone confirm that it is safe to lift the car from the front cross member and rear differential?

I've always wondered this as well as i like to support the car with an axle stand as well as the trolley jack. Couldn't really find anywhere that looked great to put it but i usually just place an axle stand near the jacking point for safety in case the trolley jack gives way.

I would not do it. It is to easy for the jack to slip and do major damage. Only lift from the proper locations.

My W209 has an identical front jacking point (block) located in the center of the front cross traverse of the front axle carrier. The jack must be capable of lifting 2 - 3 tonnes. My WIS confirms this place for the W209. Your model is not covered in my WIS, but as you have the same feature, it must be the front jacking point.

About the rear, the WIS drawing shows lifting at the diff. It might seem surprising, but there is not much weight at the rear of the car. I would use a block of wood over the top of the jack.

I assume that you are not going to work under the jack. It is only to get the jackstands in place, right?

Thanks, this is the confirmation I was looking for. Don't worry, I have a made in the USA Lincoln floor jack and I've lifted many cars over the years. I always use jackstands. The jackstands I like to use for Mercedes have flat tops and fit perfectly under the four rubber jacking points on the sides. As I've stated in my first post, the problem with lifting the car from the four side lifting points is that I can't put my jackstands under those points if I'm using them for the jack.
