c300 4matic
Floaty supsension. Shock/strut replacement @ 50K? Suspension questions.

Hello all,

First post here. Just picked up the wife a 2010 C300 4matic with 50k miles. The suspensions seems very floaty compared to our other cars ( S4, S5 and 964T all on H&R coils). Since this is the 4matic, I am planning on lowering the car with H&R SS springs and 5mm pad for the rear. Should I replace the shocks and struts at the same time? Seems like I should or is this car a bit more floaty for comfort reasons? Thinking I should probably switch them out while I have the suspension out. Is Bilstein the way to go for the 4matic?

Driving all those audis and a Porsche, not surprised you feel the Benz is a little "floaty"! Do you have the Sport version or the Luxury? My C-Sport, although not a 4-Matic is certainly not "floaty", but also not as hard and uncomfortable as the two Audi A4s that I've owned in the past. Drive iot for a while and appreciate the ride and handling....Also done 57,000 miles now, only ever needed front disc pads and discs.

c300 4matic
Can't say I love it compared to the other cars and it is the sport version! Just wondering if the shocks and struts are toast? Seems like 50k miles is usally a good time to replace and since I am going to be swapping the springs, wondering if I shouldn't upgrade the shocks and struts too at the same time?

You're comparing apples to oranges here. Yes the stock suspension is a bit floaty on the C, especially the rear. I just did springs on mine at 35k miles and it fixed the issue for the most part. Shocks/struts usually go for about 60k miles, so if you're having someone else do the work, you might as well have them do both. Bilstein is good, a bit too harsh though. Koni is better from personal experience, especially with the adjustable dampening.

Yeah, I understand that. Anyone have part #'s for Bilstein and Koni shocks and struts for the 4matic? I'm having a hard time finding anything that will work on the 4. I'm just going to go ahead and swap them out

Hmm, can't find any information on the Konis. Just rumors that they're coming out with Koni FSDs for the w204 at some point. GL

Bought mine at almost 50k and when I go over speed bumps I hear a slight pop in the front suspension. I dont know if I'm describing it right. But I wonder if I too need to get new shocks. The dealer supposed to have done a full inspection on the car a few weeks ago and told me everything is fine on my car. Should I be worried?

My 11 had a pop/rattle in the front suspension and they have apparently updated the parts..

I believe there was a TSB for the front strut mounts. Do a search on the forum and I'm sure you'll find it. You might be out of luck at 50K miles getting it covered though.

Thanks. I will check with my SA as well. I'm still under 50k so I think I'll be ok.

Doing some searches I found this right away. And the way the OP described the noise is on point. He got it replaced under warranty.
