Supercharged bearing installed and wow!
I just got a new Nachi nearing installed and the chirp is now gone and engagement is so smooth. I highly recommend this to anyone with the chirp. DO NOT REPLACE THE WHOLE CLUTCH ASSEMBLY AS YOU CAN REPAIR IT.

I know this may have been covered in one of the numerous other threads on the issue, but what's the latest source for the actual Nachi bearings and shims?
I have some here that should be suitable replacements but they're marked as "JB" on the box.

For what it's worth, the bearings I have here are in a box Marked JB Air Conditioner Bearings, part #DAC32550023.
I bought these quite a while back per suggestion online and haven't even got around to installing one yet.

I'm going to compare the Nachi bearing to the one I got from the Houston bearing supply place, the JB brand, and see how they measure up. I read that this other bearing works as well but I just want to be sure before I tear the clutch assembly off the car.

did you have the same bearing as in the ebay link? I see in the link that it is 2003, will it work for later S/C models or latest design if any released by MB ?
What is the shim material? does it have part number?

There are multiple vendors on ebay just search E55 bearing. As for the shim material I have no idea if there is a part number for it. I will try and find out.

Here is an interesting link regarding the same issue recently on the SL forum. https://mbworld.org/forums/sl55-amg-...-bearings.html
My experience with shims is they are a short term fix only. The additional shimming takes up the space lost from the worn away clutch material. Apparently some people have had success with it though. MB introduced a shim pack to deal with the chirp in the early days. They discontinued it. One can only guess it wasn't super effective.
I also think it was the shims that at least temporarily solved the chirp for the OP, not the new bearing.
