After noticing some occasional front squeaking noises (06 C55 AMG) after riding over bumps I've determined that my front sway bar bushings either need lube or need to be replaced.
Without checking my car for the actual p/n of the current bushings, I ordered new bushings from rockauto (they sent me the split version), but now I have read that a lot of people have issues fitting them because they are the wrong design (they purchased the "old" version, but are using the "new" version bracket). After some digging, I found there are 2 versions of the front sway bar.. the first is the kind where the bushings are split and can be removed (old version) without removing the entire bar and the other version where the bushings are vulcanized onto the bar (new version) so you cant replace the bushings (other than the glorified dust covers) without replacing the entire bar.
So I'm asking if anyone knows what part numbers go to which version of the bar/bushings/brackets? (I will update what I have below after I look at my car)
Bar (New): A2093230165 (23 MM)
Bushing (New): A2033270090 - aka dust cover gaitor
Bracket (New): A2033232740

Early bar was 203-323-44-65 (22 mm) 203-323-43-65 (21 mm)
All brackets for C55 show to be the same.
C32 early brackets were 203-323-11-40 left and 203-323-12-40 right.

Excellent thank you - i updated my original post as this will help if I have to reorder my bushings (or bar) if it comes to that
Updated to reflect 23mm bar.
As for the Siberian bushings, I'd 100% go for the poly bushings, but for w203 they only have 20-22mm ID.. unless the 22mm fits the 23mm due to rounding differences?
