C55 AMG Limited Slip Differential Interest




I just spoke with Ryan @ Wavetrac (Aliso Viejo,Ca.) inquiring as to why they don't manufacture and market a limited slip differential for the C55 AMG. He stated there is no demand! I then asked if Wavetrac ever conducted a market study to determine what demand there might be? He said no!
I asked him what he needed to determine what demand existed and if there at least 20 to 25 car positive response; obtain a factory stock C55 differential to determine what would be required to build LSD; then them manufacturing cost could be estimated with a possible group buy price.
So, here's the thread to determine the market demand for a LSD for PL Members. If you're seriously interested, please indicate below with your name. By the way, they market a LSD for C63 at $1,095. Let's make this happen!!! Here's their url http://www.wavetrac.net/application.htm

I suggest you pm member ROLLNNN, he has a Wavetrac in his CLK55 show car.
See post # 26 https://mbworld.org/forums/clk55-amg-clk63-amg-w208-w209/566284-rollnnn-s-2005-clk55-build-thread-2.html#post6252645
Good luck!

Different part numbers.
The catalog does not show the gears themselves. It shows the housing, back cover, and outside attachment parts. One parts interchange example shows the yoke on the front of the pinion fits the C55, CLK55, SLK55, and SLR.
Interestingly, the CLK63 yoke fits nearly every RWD car since the 203.
When I blow the filters out of the catalog things get messy. None of the diff parts interchange with anything other than a 211 or 209. Oddly, when I blow the filters out of an SL55 I run across a differential (rotating part the ring gear bolts to, not the assy) that interchanges with a C320.
That doesn't mean a whole lot coming from Mercedes. They enjoy engineering stuff for lack of a better reason.

Thanks for the reply........If I can get enough interest (at least 20 serious buyers) and provide a C55 OEM differential, Wavetrac will research the initial cost to manufacture and, hopefully, a group buy price, then we're in business!

I don't really know...........At this point, I'm only concerned with an LSD for C55 AMG's.........

According to EPC, the clk55 amg part # is A 209 350 85 64 which is identical to the C55, too! However, as with the C55, this part is only available as a reman with a core charge.

this seems to be "cost" from most places, i wouldnt go buying until i can verify that it indeed is correct, but i am ALMOST positive there will be no issue.
You guys on the FB group? c55 amg(w203)




Ok.....looking forward to your comments after install.....
Thanks....

dorimaster, I am just about to order a Wavetrack for my C55.
Does your Wavetrack fit okay?
Frank
also wanted to swap for more agressive gearing but appears aftermarket is the only way to go and with some people saying it makes noise and requires machining, i dont think i am going to, anyone else wanna chime in?
thanks

Obviously changing the side bearings would give a longer diff life before it would need an overhaul.
However, changing the diff carrier AND the bearings might increase the risk of changing the side-bearing preload, which could mean changing and machining the circlips which also act as shims.
Since my existing side bearings are in good order (no noise), I plan to reuse them.
My Wavetrack is intransit and all going well, I plan on start the project next week.
I will keep you posted.

When I ordered the Wavetrack (48.309.185WK) for my C55, I was told there would be a small amount of grinding required to fit the new diff centre. The Wavetrack is now in the housing and I did have to grind a small section to the left side of the housing, as shown at the bottom of the image. The backlash is .19mm which is over the maximum amount (which I believe is .16mm). I will seek advice from a diff engineering firm, to see if this is acceptable, or if the circlips/shims will need replacing/machining.

For what it's worth, you're not getting an accurate reading with the dial indicator in that position. It is at too much of an angle to the movement you are measuring.
Reposition the indicator so it can measure the full value. Maybe poke it straight in on the extreme top or bottom of the gear or sideways across the back of the gear on the tooth sticking out the farthest.
What does your gear contact pattern look like? There's a good chance the pinion gear needs to move in or out to match the new bearings and carrier.
Be aware that used gears rarely give you the best contact pattern but checking it will still give you an idea of what is going on.
I used the existing bearings since they were in good order and I also wanted to minimise the risk of having to reshim. Looks like that didn't work!
I will check with an engineering firm and if recommended to put new bearings and reshim; that's what I will get done.
