It’s funny my parts page lists different numbers for the lower control arms for the pre facelift and sedan as opposed to the coupe.
the coupe part numbers are as is listed by blkrkt
but the sedan and pre facelift lists
2043304911 left
2033305011 right

I am not aware of any differences between the pre facelift or coupe/sedan that should warrant a different part number. Definitely in expected

 

Interesting find.
Sedan/PFL parts are $90/ea ($280 vs $370) less expensive on https://www.mboemparts.com/ Maybe some cost savings for the Facelift folks if the parts are in in fact the same.

 

Thanks, what is the other arm in your image?

 

Thrust arms

 

In the SDW thrust arms, who's balljoint do they install? OEM?

 

I also own a 2008 C200K and at about 115,00km I replaced all 4 bushes (item 10 and bushes in item 11).

The reason I did this is fluid started leaking from the big bush item 10 in the alloy caster arm (it is fluid filled to dampen movement), it was quite a job with out speciality puller tools.

When the bushes item 10 were replaced I straight away noticed the steering wheel was not pulling to the road side like it was before.

Removing the bushes can cause galling of the bush hole in the alloy arm.

Looking back I would not do this job again but would replace all 4 alloy arms with new genuine part assemblies and would not contemplate aftermarket bushes or exchange arms.

 

Bringing this thread back up, because I have now a good amount of miles and potholes on the thrust arms and looking to get the lower arms with synchro mono ball.
are the lower ones bringing NVH in ?
the top ones bring steering feel and sharpness.
the arms come not OEM, from Synchro, but from Lemfoerder.
Lemfoerder is known to be the OEM for suspension bushings and arms for Mercedes. It’s a level above the aftermarket.

 

Been trying for months to get Syncro to do the bottom ones but no luck at all. I told them id even pay for brand new oem arms to do them from too.

 

yeah I could never get them to do me some either. They just sent me a link for the thrust arms which I already have

 

PowerFlex and one other company I can't remember the name of make polyurethane bushings for the lower control arms.
I ran the PowerFlex 95A bushings in my car for a while. The made the turn-in sharper and the car held its line better under hard cornering.
But, the car also had a little not-quite-snap oversteer in certain situations that made it unpredictable when cornering hard. I ended up going back to stock replacement bushings. The car is noticeably softer and more wishy washy with the stock ones, but it doesn't do anything weird halfway through the corner.

 

Arms are OEM, AMG-stamped. I suppose you could get the Lemfoerder but why.
The monoball in the LCA did not introduce any NVH, but the ride quality is pretty unforgiving.
Handling and feel are both greatly enhanced. Razor sharp.

 

where did you get yours? Your lowers have the sdw bushing in them right?

 

Got them from SDW. Yes, have the monoballs in both the thrust and LCA.
