Good info, I'm curious is the clk55 diff stronger than the stock 43? Also is the drive shaft larger/thicker or just an extra finger on the flange?

 

Superb , about halfway down this page http://www.club202.com/forums/showthread.php?18851-C43-CLK55-Conversion/page3&styleid=6 there is a comparison of the c43 and clk55 prop

Diff is larger 220 case, 2.82 ratio,

The clk55 prop, diff and axles is same as w202 c55

 

Paul,

When you swapped to 2.82, can we tell that ECU/TCU can be programed to other diff. ratio..?

Zayed,

I have tried some coding on C43 ECU and E55 can be coded in ME using 9 digit code,I think you need developer to be able to clear factory code. however it does give some fault codes so would need further testing. because I don't have gate shifter anymore it is hard to test 98/99 C43 ECU now. I assume if you code to E55 then the 2.82 could be used, also E55 map would apply?!

Cheers

 

Excellent, Thankss for input Paul..

Guys,

Finally got my prop shaft last week only had to wait 2.5 months!.. I'm really glad I went with an entirely new shaft.MB germany said there was none availible world wide so they had to make it, smells like it has just been painted and date shows it was made 28/1/15

Both my original C43 and CLK55 shaft had this vibration 60 - 80km's but the C43 was not as bad I though it was wheel related at first, I recently checked the old C43 shaft and it too has dry notchy universal and spline.

Comparing the old vs new CLK55 shaft with 149kkms in hot climate,all original parts:

Old shaft had some lateral play in center bearing and rubber has gone a little firm but was smooth/quiet,zero play in new and rubber is very soft.

Old shaft had dry spline and some play,adding grease helped alot,new shaft is VERY tight, zero play.

Old shaft has notchy dry universal, new is smooth.

Old flexi disks were like concrete, new are soft.

Old shaft has dry worn centering bearing rear prop to diff, wear pattern shows it was no longer center and rubber seal has expanded to far to retain grease. I suggest a check for this would be to safely jack the rear wheels off the ground and let the car run in drive at idle,touch a small plastic tool onto the side of the prop just prior to the diff as it rotates and you will see if this bush is doing its job, on both my CLK55 and C43 it was off center.

As for the prop to trans centering bush, it has expanded slightly on the old, but this bush is rubber only and still had some grease present.

Here is a pic showing the rear centering bush, you can clearly see the seal has expanded larger than the shaft so this has lost all grease. I suggest this should be replaced when flexi's are done.... however I would evaluate the rest of the shaft before doing anything as it might end more cost effective to replace the entire prop shaft.

I am yet to drive the car as the new shaft didn't come with new bolts for trans and diff even though it comes with two new flexi's , so just waiting on bolts.

 

Interesting! What was the cost of a new custom made C43 prop shaft? ??

in other news, i ordered a clk430 shaft for mine. Identical!

 

Yep sure prop in clk430 = C43 ,clk55 = C55 plus nearly all other parts.

Have you investigated what is wrong with your original shaft?

Not sure what you mean by custom?

 

Maybe "custom" is the wrong word. But MB had to go build a one of a kind shaft for you, since no others were available worldwide! That's basically custom built OEM just for your car!

 

I guess so.. but it is same prop shaft used in 208 CLK55,they had just exhausted all stock so cost same as if they already had one!

 

I think we can use CLK55 shaft in C43/CLK430, just need to change the tranny & diff. flanges from "3" fingers to "4" fingers, is that right..??

ZAYED,,

 

Hi Zayed,

I think front prop shaft will be ok but not sure about rear half as diff is larger maybe the flange is slightly further forwards?. I recall when I compared C43 to CLK55 I did not notice any difference in length but the difference could still be small

I will compare them again some time when I have both together

 

Hi Paul,

Yeah, i think length are the same, when you able to compare them let us know..

ZAYED,,

 

hey guys nice thread, I am looking for some tips my E 55 is doing a strange clonk when starting in D from the rear it is ONLY when engaging from D stop to start rolling if changing from C to S or M is not that bad but specially when in C Cruise I hear this large clonk if I quickly floor it, can it be the Flex disc it seems has small cracks did order new one but have a hard time finding a DYI remove/install but from WIS is not that great really

Any tips on the remove install but mostly on the noise, I never hear it otherwise but when from totally stop to start hard acceleration..

 

Your E55 looks nice MaaaaaN..,

i prefer to ask professional guys in W211 AMG section..

ZAYED,,

 

Thanks bro, just got new black grille + rear lip black and black emblems
went from the CLK 320 2000 what a change

thx I will try the AMG section bro, urs isnt bad to man,,,
