Front sway bar bushings
My '02 C32 has bad creaking from the front suspension when braking hard or going slowly over bump. I just replaced the end links and the noise are somewhat improved. But I can't figure out the correct part number for the sway bar bushing..
According to EPC with my VIN, it says my sway bar is 23mm but with bushing part number indicated it's for 22mm bar... A203 323 16 85, and the part number are replaced by A203 323 22 85 which also indicated it's for 22mm bars...
I also read that lots of C32 owners replaced it with A203 323 25 85 which is for 23mm bars that's also listed as C32 parts under different VIN. My question is, should I go with A203 323 22 85 or A203 323 25 85 which seems to make more sense even though the EPC called for the 22mm ones? Will the 23mm one ruins something if it happened to be wrong? Thanks!

So when you ask for the replacement for the two bushings you will get a total of 6 rubber pieces.

btw it completely eliminated the squeaking.

or, you could just pull the front sway bar off, remove the bushings, apply a good coating of white lithium grease(this is what i did) or something that will not deteriorate in the short term, then reinstall the sway bar...should not take you more than 30 min...

I wish I had saved the parts receipt from when I changed mine recently so I can give you the number. I do know that I went to my dealer with the VIN and asked them to pull up the proper "rubber bearing" (that's what it is called). I'm sure you know this but the part has been redesigned so that you not only get the rubber bearing that goes on the bar but for each bearing there are two rubber sleeves that protect the grip surface of the bearing from the elements. I believe that the -2585 number is for those new sleeves (going solely from memory here).
So when you ask for the replacement for the two bushings you will get a total of 6 rubber pieces.

Hey,
I found the receipt for the parts. The replacement rubber bearing (commonly referred to as the sway/stabilizer bar bushing) is part number 2033232585.
The rubber sleeves that are part of the redesigned bushing are part number 2033270090 (you need four of those, two for each stabilizer bar bushing).
Each stabilizer bar bushing has a groove on either side of it, and each sleeve has a lip that fits into the groove on the bushing. Two sleeves per bushing. You must disconnect the stabilizer bar from the link rods so that you can slide the sleeves on, then you stretch the lip of the sleeve over the bushing BEFORE putting the "U" shaped holder back on that bolts the stabilizer bar to the front axle carrier.
Regards,
Pete

Thanks for the info guys.. Looking at the EPC, I was wondering what the heck the 2033270090 'boot' was until now haha, thanks! I think that's a rather strange fix if you ask me..

At least this is what MB says, and my service and maintenance DVD specifically says NOT to grease the rubber bushing due to the possibility of breakdown of the rubber.

Wait.. Are you saying the the original bushings weren't greased??? I always thought that all sway bar bushings are greased? At least that's the case with my previous/current other cars...

Well, not to doubt what 1FAST talked about, but grease on the rubber bearing can possibly do two things: one, it can attract grime, and two, it can deteriorate the bushing leading to excessive play or a loss of stabilization from the stabilizer bar.
At least this is what MB says, and my service and maintenance DVD specifically says NOT to grease the rubber bushing due to the possibility of breakdown of the rubber.

i wish that we could get some polyurethane bushings for the sway bars...rubber is just worthless in my opinion

That means no mess, no maintenance-just bolt in H&R Sway Bars and go!
Like all H&R components, H&R Sway Bars are 100% made in Germany, and are powder coated for long lasting good looks and durability on the street and track.

I have this problem, also. The rattling squeaking, etc. I suspected the bushings had gone bad.
The dealer determined that my car had an incorrect swaybar fitted. I think they had troubles with the bushing fit, and that's how they discovered it.
I am waiting for the correct AMG bar to arrive from Germany. I am assuming the dealer knows what they are doing, but I occasionally wonder if they just had the wrong bushings! Luckily it is all on warranty.
I've had this car since new (the second one in Dallas!), so I know no one has modified it
