Studded tires are illegal here. If I could fit my car with studded tires, I wouldn't need any of the LSD/ASD/ASR stuff

I've driven an ASR equipped car and just let me tell you this - when you're driving up a snowy hill and one wheel has really poor traction, ASR won't be able to help you. It just cuts on the power, but it's no use - you're going slower and slower up to the moment when the car stops, traingle flashes and nothing happens.

It's a whole different story with ASD, which locks the diff and will take advantage of any tiniest bit of traction on any of the driven wheels.
Of course - a 4matic would be perfect but there's always a price to pay.

That is exactly how I am planning to do it! Get a complete donor with working ASD and transfer the whole system - bit by bit with the cars standing next to each other for as long as it takes.

Maybe you'll find it surprising, but it's actually very very hard to come by a W124 in good shape in here. To find a car in mint condition, with original paintjob, less than 200KKm, Us-level equipment, fully serviced with a maintenance booklet (like mine) would be a miracle. And then, when the miracle happens and you find such car, you have to pay big big money for it... You can buy an old rusty W124 with working ASD cheaply though.

The only thing I am concerned about is - whether my 2.65 diff with an ASD carrier is going to work with the system. Housing is the same - ASD generally works in the area of the flanges (?). Nevertheless I've seen ASD diffs to have a sort of a metal line connecting the right and left flange and I am not sure which element this could come with.

For example here(even though this is actually a 185mm diff):


I don't see it in the EPC:



Does the hydraulic system connect to the flanges?

Thanks for all the information.

Dave, by viewing your site, reading all those articles and seeing the modifications pictured I've really entered a new era in my Mercedes adventure. Thank You for that. I am learning something everyday and when I cannot figure something on my own, there are few things that your site or the forums cannot help with.

AMGDave

D'oh. Well, studless snows are almost as good... I assume they allow those, right?



You gotta hit the snow chain switch with ASR in that case. This allows some wheel spin. Otherwise you'll end up stuck as described above. With bad tires, even ASD won't help, you'll sit and spin both instead of one. Tires are just as important as the LSD/ASD/ASR/etc system.




It only locks the diff if the clutch pack is good. When the clutch pack is worn out, the ASD diff acts just like any other open diff, even with the hydraulic pressure applied. 4Matic uses ASD as well, btw; it's part of the system (at least on the W124 4Matic).




That is sad!



Not sure I understand what you mean... the ASD carrier is plain LSD. The ASD system really consists of the external hydraulics, pump, and electronic controls.



It connects as shown in the photo. A flexible hose from the chassis connects to one flange, and that little pipe connects the two flanges (actually, ring cylinders) left to right. The pipe is in a different section in the EPC... Group 32, subgroup 285, page 2.



No problem at all! Happy to help lighten your wallet, lol...

chlippo

can we change the clutch pack? if so where to get it?

AMGDave

Oh sure, you can buy all the parts to replace the clutch pack from any Mercedes dealership. But it is a LOT of work, and some special tools will have to be purchased or fabricated. Pics on my website (here) show the various tools, as well as the clutch discs. All the discs have to be purchased individually. Probably $250-$300 in parts depending on where you buy them.

ruslan98270

got the diff installed, and custom made axles, whole set up costed me 35$ for spare subframe, got free diff, so 35$ + day of work

Hi everyone,

I have a 300-24 with a 3.69 diff and am interested in the quaife LSD.

There was a previous post of which ratios would work with the quaife but I thought it best to double check.

Any opinions on running the quaife on the 3.69?

Or will the 3.07 be the closest option for plug n play?

Thanks.

AMGDave

The Quaife QDF5V is plug+play only with early 210mm diffs, and only with 2.65, 2.82, and 3.06 ratios. For numerically higher gears like 3.69, it might be possible to install with a custom ring gear spacer and longer bolts, but AFAIK nobody has attempted this yet. Side note - I am not aware of any 3.07 ratio in 210mm size... 3.07 is a common 185mm gearset.

khayman

Ah, so my fears have been confirmed.
It looks like the 3.06 is the one that I will be looking at, and with it the meter as well.
While the response of the 3.69 would be great, custom is too hard left!

p.s. Dont think anyone has tried a wavetrac lsd?

Best

Jan AMG

Hi! I'm trying to solve the same, I have a 300 CE-24 ASR 3.69 and looking for a real LSD. Have you been successful in finding a solution?

AMGDave

As noted in previous posts:

You can bolt in the factory Mercedes clutch-type LSD, but Quaife doesn't make anything for the 3.69 gears. You may be able to have a precision ring gear spacer machined to make the Quaife work but this would not be an optimal solution...

Jan AMG

OK, thanks. Where to get the factory Mercedes clutch-type LSD? Do you mean ASD?

AMGDave

Any Mercedes dealer can order the LSD for you. The part number is on page 4 of this PDF file. Current price looks like approx $1065 EUR excluding VAT.


No, I do not mean ASD. Please read the rest of this thread for an answer to that question.

Jan AMG

Very helpful!!! Thanks million times What amazes me E500 1992-1994 has only ASR.

$1065 + VAT looks like a quite friendly price to me. I was told $4,200 + VAT by my local MB dealership for the original ASR.
Are you saying all I need is to order this part no. 140-350-29-23?

The reason I started looking for a new dif. elsewhere was the old one has one Prop flange leaking (A 129 350 09 45) and MB cannot order a new part anymore ($350). They offered me a new dif for this incredible price. Hence I started looking after solutions and realized letting go the ASR for LSD might be the best mod ever..

Jan AMG

Sorry I meant this: 124-350-91-23 (I guess 3.67 vs. 3.69 won't be a big issue)

AMGDave

Your 300CE-24 should be a 124.051 chassis, and should have a 210mm ASR diff, which would use LSD # 1403502923 with 3.69 gears (click here, enter part number to get pricing).

This is NOT a complete differential assembly! It is only the center section, the limited-slip unit / ring gear carrier, as seen in the attached photo. You would have to install this in your existing differential. Photos of the process are shown here.

If you have a leak, replace the seals. The flange should not need replacement unless there is a significant groove worn into the shaft from the old seal (which is highly unlikely). That ~$4k price is for a complete new or rebuilt differential assembly, and it wouldn't be LSD... Mercedes never offered ASR with LSD together. ASR is "electronic LSD". You can read more about ASR vs ASD function here, and LSD function here.

My LSD with 2.82 gears is up for sale in the classifieds. Built from the ASD non-ASR differential from the 300SD. This will bolt right into a V8 car but if you have ASR, it will not function.

https://mbworld.org/forums/engine-pe...-82-gears.html

AMGDave

FYI... the non-ASR diff is best for non-ASR cars. If you install this into an ASR car (like a 500E), you will not have either ASR or ABS functioning. The ABS diff has a single speed sensor at the pinion, the ASR diff has two speed sensors (one at each axle shaft). The two are not interchangeable.

It's a GREAT deal for someone with a non-ASR 400E though! I'd be all over this if it were an ASR housing (my 1995 E420 has ASR).

rivcal4life

I called Eric today to tell him about this. He has TWO non-ASR 4.2 liter cars. Too bad he was sick and unable to come to the phone. :-/

dernt

I know Eric had one of his 400Es running 14.4 with stock gears and an open diff. If he still has that car, and is interested, I would ship it to him for no extra cost (I'll pay shipping) if he installs it, and reports his ETs. It would be cool to have a 4.2 break into 13s.

rivcal4life

He was under 4.4's last I remember! I will relay this. Pretty certain he'll take it.

AMGDave

I'm not certain, but I think someone else already has dibs. (?) Tell Eric to get off his duff and back on the forums! He hasn't posted in months.

I'm looking to get the CLK 430 differential (198mm, 2.87 rear) to 3.XX+

I don't have abs or asr installed. No computers or abs in the vehicle.

What are my options? Sounds like I can just get the ring and pinion 3.27 or 3.69 from the w124 with 210mm diffs, and swap that into my housing, correct?

What is the lsd option for 210mm, if no electronics need to function?

MaxMatt

I would say W208 and W124 rear ends are not that easily interchangeable.

CLK 430 has 2.87 diff ratio.

Why not just get a diff from W208 320 (3.07) or 230 Kompressor (3.27)?
CLK 200 had a 3.46 or even 3.92 diff ratio.

Quaife offers a bolt-on TORSEN-type diff for your application.

Jbell

I have the 208.370 body, uses 198mm gear.
the kompressor uses 185, and 320 uses the 198mm

so the 320 may work.

AMGDave,
I just finished reading all 9 pages. Respect and thank you.

Please correct me if im wrong or confirm that what i plan is doable.

I drive a W123 280CE with a 200D diff. (3,96 gear ratio)
I use it on trackdays :
I desperatly need LSD in my diff.
On peachparts forum I learned that 3 guys have build LSD diff in w123 casing using a W201 2.3 16V diff carrier, and a 5 mm spacer and longer bolts.

Attached you see pictures of the diff i purchased, its suppose to be from 86k miles W201 2.3 16V, with ASD.

Am I ok to start dismantling both diffs W123 200D diff (3,96 gear ratio) and W201 diff with asd ?

both diffs are around 14cm wide. but the w201 carrier seems a little wider, and inside of a w123 diff there seems to be not enough space, and Im affraid that the carrier position will be to much to one side , after we machine out the inside of the w123 diff.

I might be writing nonsense, i have information oveload,
I payed 200 USD for the diff.

Can I use W124 ASD diffs ? they come much cheaper ?
W201 is 185 i guess thats why i had to pay extra for a 16V diff, any compatbile W124 asd diffs i should be looking for ?
