Rear Leaf spring bushing replacement on 550SD

hi all,
i have a 2015 550SD gaser.

rear bushings are squeaking really loud.

looks like the bushing (i THINK this is what this part is called)

is replaceable.

ive greased it up...and its quiet for now. but i want to replace to have it done right

Any suggestions on how to do this??

That's just a snubber for the upper overloads. With that grease there I'm skeptical it's squeaking.

If you really wanted to replace it I honestly don't know if just the rubber is available. Looks like the bracket is riveted, so maybe.

I'd keep searching, though. Spring eyes, shackles, shock bushings. Maybe even e-brake cables.

I guess if you wanna experiment, jack up the frame to unweight the suspension enough to cram a thick folded rag or something else in there. Do a short test drive. If the squeak remains, it's something else.

edit: apologies you said the grease quieted it. Long night. If you do find a part # for just the rubber, let us know. You might be able to swap the rubber side to side -- I can't tell?

SOLUTION:
i did buy the rear helper spring bushings: see the pic.

1) jacked up the truck FRAME
2) cut off the old bushings
3) slipped on new bushings.
4) no more squeak.

FYI
