I've got a later W126 (1991) and am redoing the rubber on it. I've got most of it apart, but am having trouble finding a tool to remove and replace the rear subframe bushings. Mercedes calls out tool 126 589 01 33 00 and I am having a hard time finding an aftermarket tool.

Also, I have a question on the trailing arm bushings. The outer bolt is hard to get to. My understanding is that I may have to remove the from of the subframe (where the bushings are) to access this bolt. Any other way?

If I remove the front of the subframe and put the trailing arm bushings in, then I am supposed to make sure the axles are straight before I tighten them.

Well, to make sure the axles are straight, that means to me that I have to have the subframe and axles bak in position to make everything line up. Once the subframe is back in place, I have the same bolt access issue - I can't get to that bolt - so how then so I tighten it while keeping the axles straight?

Probably overthinking this, but I just want to have all my ducks lined up.
