hello

first, im not so good in english but hope u guys understand.

i changed my differential oil for some few month ago, because it started to ''singing'' when i was driving.the oil did not look good that all! now it started to make some strange songs when i dropping the gas and let the engine ''brake''. and some time the song comming when i driving normal in for exempel 50 mph. im 90 % sure that the song comming from the differential. because yesterday i drained the diff oil again, and the oil look wery bad! MUCH small steel particels comming out with the oil and the oil was grey/black with some gold coolor!

now i think i need to change the differential soon, wich car can i take the differential from? i have one w202 220 DIESEL but i guess this dont have same differential?

my c36 have a 5 speed transmision. and differential is a ''open'' with no loocker.

and how is the jobb to change the differential ? much jobb? what need to dismounting to get is out?

thanks for any help!

I don't know if the diff was different for the 4 speed models, I assume not, but I have a 95' C36 diff for sale if you want it. Where are you located?

And to replace the diff, the rear end must be dropped. So the 4 subframe bolts come out, brake lines off, and wires, and disconnecting the rear flex disk. Not sure if any of the suspension arms are attached to the body. But it's a relatively involved job. Need a lift, or a pretty damn high jack

when replacing the rear diff the subframe does not need to be removed. the axles need to be unbolted it should be a 12 0r 14 mm triple star socket. then the driveshaft needs to be unbolted from it. then there are 2 bolts that go through the subframe and bolt to the back cover of the diff. and 1 more mounting bolt in the front of the diff i believe its a 6mm allen. the diff will come out after that

Thanks for good answer! But from wich mercedes w202 can i take the diff from? Does the c36 have a special strong diff, or is this diff used on some other moddels?

Nd4spd13: im located in norway :/ i think shipment is way to expensive

Is your C36 comes with 3.07...?,

and do you have "ETS/ASR" or "BAS/ABS"...??

ZAYED,,

aceracer666

Im not sure witch ratio i have:/... i have 97 with 5 speed transmission...

I have just abs and the switch for turning off asr i think it is..

cm60k

I believe you have 3.07 end, with one speed sensor in the left side of the diff. housing,

can you confirm that..?, it will easier to help....

ZAYED,,

aceracer666

I found a number on the down left side on the diff , last number was 3.07 i belive thats the ratio?
The sensor i did not se but i could not get my head so far under the car without a lift å jack..

cm60k

Yes, 3.07 is the ratio,,

many models that has the same 3.07 you have,

(W202 C200 CDI, W210 E200 CDI, E200K, E280, E320, E280 4-Matic, E320 4-Matic)

also you can fit the one from "W124 or W201", just may need to replace the side flanges & front housing,

our friend Money-one replaced his diff. with LSD from "W201 v16",,

there are many choices you can go through, it depend to you, if you want to replaced the internals or replace the assembly diff...



ZAYED,,

aceracer666

Oh nice! Strange.. are all this diff posibole handell the power from the c36 amg? I was thinking the c36 had a special strong diff..
But if i can use from all this cars then it should not be any problem to find a "new"! Are this diff bolt on?
Thanks for good helping! Mabey i ask more quetsion if i need.

cm60k

Sure, if you choose any of the list above, it will 100% bolt-on,

but if you want to replace the internals, you can go with any gear & pinion that has 185mm with 3.07.....

ZAYED,,
