It fits the older 210 differentials from the w107 cars up to the w129-w140 case. Also used in the w124 w210 etc. At around 2000 Mercedes switched carriers to a wider unit. This uses the qdf7v. Still a 210mm carrier. They are roughly the same price. The qdf9v in the 215mm case is 1000.00.
Honestly at the additional price for the Quaife I would still buy it over and over instead of the factory 210mm lsd that was in the old cars. It lasts about a day or two if you drive it hard and has pretty low lockup. Then you have to buy another or rebuild it. The Quaife unit has a lifetime warranty. Has no clutches to wear out, is seamless in it operation and has torque bias to what you need to keep both wheels pushing hard. Absolutely the best upgrade I have ever made. I recommend it to anyone making more than 50hp.
As far as cost goes. I know it is expensive. But we are in a limited market. Especially in the older units. It is all volume sales. A couple of years ago the qdf9v was down about 200.00 from where it is now due to srt8 cars using the same diff. If we get volume up on the the qdf5v then costs go down. Right now I order them one at a time from the UK. If I remember right 10 or more starts making significant savings. Like 15%.

I can appreciate what you are saying but if I want to stick with my 2.24 gears (or even step up to 2.47 gears) the Quaife isn't even an option for me, correct?

Eric,
I did not know you were expressing interest for yourself. No you can not get a quaife for the 2.24 or 2.47 gears. You would have to go to the 2.65 gears.

For the options for the sl600 rear, I will check. I was thinking that you could just get a 2.65 diff from any of the old cars and set the gears up in a standard 107 case. I think that most of the later e320 w124 cars came with the 2.65 gears.
For the tcu change. You can just change the tcu for one with the transmission and gears that you want. I am not sure about going past 2000 with the new egs though. I think you can do that but require the shifter to do so. An w210 e55 came with 2.82 I think.

Here is the qdf5v app list from the epc. All models listed with the correct carrier.

I think this is the one. 2005 E55 comes with 2.65, but the front mount looks weird.

He also has this in case anyone is interested:

Yeah the cls, e, and sl use a very different front mount. The diff bolts to a cross member that is about 2' long and that bolts to the subframe. Real pain because the exhaust has to be pulled to get it out. The all other chassis use the standard design. Including Chrysler.

Roncallo · #21 06-05-2012, 10:43 AM

Wow

I just realized EPC only shows that differential as an assembly so swapping gears into an SRT unit is unlikely.

You can get the parts. The bearings and other parts are listed under other models still. Also the srt8 guys swap gears all the time. Richmond makes gears for both the 210 and 215 cases but much higher gears than you want. If you just want lsd and 2.65 gears then the cheapest would still be getting a diff out of a w124 E320 with those gears and installing the Quaife. By the time you buy two differentials and bearings and the cheaper lsd for the 215 then you are not going to be ahead. I have an ASR 2.65 diff on the floor here that I will sell you. I can even do the lsd install. I do not know if the teeth count is correct for the traction system but I could count them. Let me know. 2.65 gears are standard on the later model w124 E320 though and non asr is easy to find also. The difference on the install is about an inch in width. Which ever one is easier. If you really want the 215mm diff though get what ever case you can find with those gears used and buy an srt diff used. They are plentiful and cheaper than the mercedes for the same exact thing. Bearings and seals are going to be 3-400 dollars.

Is the 124 diff like a 1.3L 126 diff or is it like a 1.4L 140 diff.
When you say convert to LSD do you mean Clutches or Qualife
I didn't think the ASR diffs had the machining for clutches.

whipplem104 · #24 06-05-2012, 02:38 PM

The case in the w124 is from the r129 chassis. It has a front mount like the w140. It should bolt in your existing subframe straight away depending on the rear cover plate. I would install a quaife unit for sure. I would not waist the money on the factory lsd but you could do that also. You can put the lsd in either asr or non asr. The only difference is in the stub flanges and the case. The carrier for the ring gear is the same.

I assume this is an early 124/129 1.3L case. Does it have a 4 web input flange. What is the dimensions face to face of the output flanges. Not ready right at the moment with that kind of cash but you are welcome to PM me with a quote for the unit set up with the Qualife. also I need the number of teeth for the ASR sensors.

whipplem104 · #26 06-05-2012, 04:21 PM

You can install the 4 bolt flange or 3 bolt. I will get the other info for you

whipplem104 · #27 06-05-2012, 09:30 PM

So I measured the asr diff at 10.5" to the flanges where the axles bolt on at the shop and then measured an abs diff at home at 10.25". I will double check the asr tomorrow. The abs is about an 1" narrower from what I remebmer. The teeth count on the asr diff is 32 teeth I think I will have to double check this again. Should be the same as the wheel speed sensor on the front wheels. Although you could use the speed senor system that you built for your diff with either diff if you wanted.

I measure 10.625 for the 107 diff and almost 12" for the 129/140 diff. This may require another axle rework.
