torsion bar bushing replacement
MB only sells the entire torsion bar, not separate bushings.
I took a chance on these: https://www.ebay.com/itm/387553190698, and wanted to report for you all that they worked great.
The car was on ramps, I didn't even disconnect the links... might've been a bit easier if I did but its not necessary.
It is a bit tricky to install because they are intended to be compressed to go in. I jacked up each bracket slightly until I was able to thread the bolts correctly, then steadily tightened all four. Finally I dropped the suspension to normal height, did the final few turns and torqued them to spec.
Might be easier to get slightly longer bolts of the same thread, use them to get the brackets mostly in place and then replace with proper bolts.
I don't have the active curve system, so I'm not sure the same bushings apply.

If you don't have them, get some large ratcheting wrenches when you do the control arms, like a set of 21/22/23/24mm.
It will make it much easier to get them off the ball joints, can't get a socket in there.
On the GL I've replaced every front suspension part over time, the upper control arms are by far the most difficult because of access to the bolts. Haven't had to do anything in the rear except for air springs.
