Does anyone know what the (2) large bolts and bushings are? It's right behind the rear diff on a 2008 E63 Sedan. I'm trying to tackle various creaks in front and back of the car. I get creaking in the rear. These bushings look torn and worn to me but not positive. Also not sure what they are.

on the back check your most rearward subframe bolts. You may have ripped one of the bolts out and the Subframe may be hanging low in that corner. good way to check is spinning the bolt if it ripped itself out will spin freely. I had it happen to me and I see a few others have had them rip themselves out too..
Those pictured bushing look fine to me but hard to tell from a single photo..
It been many many years, but back then I broke two subframe bolts. I could feel the rear moving around at speed and over bumps at highway. I also started noticing usual wear on my rear tires.
So I took it in, and told the SA and tech what I thought it was, and he said that I was correct, everything was replaced under warranty, but did take several days.
I was lucky, in the sense that I was aware that something wasn’t right, as this could have ended up badly. I think I even did a thread on this with pics, years ago.
Thanks everyone. Great info. How tough is it to change the diff bushings? Is it a simple replacement or a nightmare job.
Also, does anyone have a good photo or diagram of the rear subframe bolts you're talking about?
As for the condition of the bushings, I noticed that they appear to be cracked. On my phone I was able to zoom in and see what looked like jagged cracks that don't seem normal. You might be able to see it if you download the photos and zoom in.
its probably gonna be a crappy job to replace the diff mount bushings dude not sure haven't done or looked too much into it...
thread about the issue we talking about. https://mbworld.org/forums/w211-amg/...-big-deal.html if you pan the camera left or right from where u took the diff photo you would see the Subframe bushes. its just behind the rear wheels the exhaust routes just below them from memory...
Those bushing dude if there is minor surface cracks probably fine. usually bushings tear themselves to bits or the rubber is no longer stiff. I would say if you could get a pry bar between the diff and the subframe you could test for play but I imagine the diff is held in place by other components too.. I zoomed in on them they seem fine... I may be wrong but those bushings don't strike me as a high wear item?
You might be able to do the diff bushings with the subframe still on the car depending on the tools you use.
When I did them I did it with the subframe out of the car. To remove subframe, you need to remove everything connecting the subframe to the car and all other parts which might interfere.
Once the subframe is out the diff bushings are easy. I used the tool in the link to press in and out.
If you choose to remove the subframe I suggest you replace all bushings including subframe bushings and control arms so you don't have to remove the subframe again.
you need mb star to deflate the airmatic system and special tool or making your own to press subframe bushings since there are rubber parts sticking up preventing you to press with a socket. A pipe the same size as the bushing works well which you then cut to fit. I used my stationary press for the subframe bushes, it can be done without one since there are no metal sleeve but I wouldn't try that. If you remove bolts for subframe, get new bolts.
