You can buy the clutch/whatever to turn your diff into a LSD from your local dealership...I'm told.
W124 LSD (limited slip diff) options?
Hey all,
In an effort to strain every conceivable amount of performance available in my coupe, apart from a driveline swap, what options does one have when it comes to putting an LSD into a car that has an open diff? For me having one drive wheel is an annoyance and on certain occasions, dangerous. I'm certain an LSD is what's preventing me from getting the power to the ground in a tame and efficient manner. From what I've gathered through search, a W124 equipped with ASD could be retrofitted to an open diff car and have the hydraulic line blocked off to have the LSD effect without the hydraulic assistance. Is that true?
So, as W124 owners, drivers, and enthusiasts, what do we have available to us *preferably MB* to convert our cars to an LSD? Would the rear end of a Cosworth 190E swap over to the W124?
Thanks,
Allen

A member here "GSXR" is da man you need. He got me strieght on re-gearing my 400E. And yes, I need a LSD now, it just spins the inside tire. And I'm running wide sticky tires in the back, 245's I think, Falken Azenis. Great tires by the way.

1992 300CE comes with a 3.06 diff ratio. You can buy the ASD LSD carrier from Mercedes and install it into your diff, part number is 126-350-40-23, but the diff will have only a 30% lock-up.
Hmm, that's $1100 retail. Or $900 for me...Cripes, I think having an LSD is going to be an expensive affair. It's an option though! 30% is still better than none.1992 300CE comes with a 3.06 diff ratio.

A cheaper option would be get an ASD (non-ASR) diff from a scrap yard or a crashed benz, and then pull out the carrier and intall it into your diff, or swap your ring and pinion gears into that diff, in order to maintain the stock diff ratio.
1992-1995 350SD came with a 2.82 ASD diff.

You've got a few options, but each has issues.
The LSD unit from a 190E 16v will fit, but has a 3:27 R&P
The ASD unit from a 300D 2.5 will fit and has the aforementioned 30% lock up, but it also has a 2:65 R&P. It more than likely needs to have the friction discs replaced by now, if you want even that amount of lock up.
A Phantom Grip-type of spider gear spring block (see the Kleeman link above) should be able to provide some percentage of lock up. These could potentially be used in conjunction with the ASD diff for a really aggressive setup.
Really, we need for gsxr to chime in here and give us the straight dope, since he's actually accomplished this goal via a modified ASD unit.

my '95 E300 has ASD.
and I really don't care for it.

That won't work without some custom work because the 190E 16v and 300D both use a 185mm size diff. Whereas all M104 engined car use a 210mm size diff.You've got a few options, but each has issues.

And disregard my previous post, the LSD carrier has to match its specific axle ratio, so swapping a carrier from a 2.82 ASD diff into a 3.06 diff won't work.
Here's a good thread Limited Slip Differentials for W124's?? - MBWorld.org Forums
Interesting, I was under the impression that the 210mm diffs only showed up in the M119 cars. I see Dave's post in your link and provides pretty much all the info we were looking for in this thread.
Didn't wanna start a new thread, but I jus found this... Looks awesome.

Will the 190E LSD bolt in without a custom driveshaft?
Not 100% sure, but possibly.Will the 190E LSD bolt in without a custom driveshaft?
Even if it did, you'd likely end up with a different diff ratio AND you'd also have to run the hydraulic lines and install the tandem pump, hydraulic tank, etc. to drive the diff.
A lot of work for what it is IMO.
Look to Europe.. Lots of w124's with 4 cylinder engines had LSD without ASD.
Go over to the Uk boards for English, but actually mainland Europe is where you will find.
Non ASD to ASD swap is a lot of work, but for an LSD I thinks its worth it, it changes a lot about the way the car handles and launches..

It need only for ASD, not LSD.AND you'd also have to run the hydraulic lines and install the tandem pump, hydraulic tank, etc. to drive the diff.
And early 2.3-16 was available with mechanical LSD, not with hydraulic ASD, but later models had the ASD as a standard equipment.
If you set up the suspension of a W124 by starting with the individual wheel load and adjust spring rates with spring pads to get the proper weight distribution and transfer, there is no problem "launching" with much more than stock power and an open 3.07 diff..Look to Europe..

Not an anomaly, it launches this way every time from a 1500 RPM torque load...
Goes for about six+ car lengths, chirps on the 1-2 shift and settles down...
Got some hints on this Obi Wan?If you set up the suspension of a W124 by starting with the individual wheel load and adjust spring rates with spring pads to get the proper weight distribution and transfer, there is no problem "launching" with much more than stock power and an open 3.07 diff..

I've looked at using ASD. It's a ~30% lockup before the hyrdaulics are actuated, many people are just using a grease gun to manually lock it up. The cost of an ASD diff is not much cheaper than an LSD....
Same rules apply be it for a drag car or track car right on down to a street vehicle.Got some hints on this Obi Wan?
Only difference is what your final objective is...
Drag car more front to back transfer for traction, track car side to side and front to back and modified based on the track characteristics.
You start by using a portable wheel scale to determine the load on each corner.
If you are using a linear wound spring and know the spring rate you can then balance the loading with the spring pads.
What most don't realize when they lower a car, especially by removing the spring pads, they are altering the spring performance.
For every inch you compress the spring it exerts the designed spring rate.
e.g. spring rate of 300 lb/in, compress 3" and you exert 900 lbs pressure.
So if you have a 3600 lb vehicle with 50-50 weight,you have 900 lbs per wheel.
The spring pads selected by Mercedes during production are for this very reason to help balance the chassis loading.
Using the wheel loads you try to balance and determine how much travel you want in the suspension for weight transfer both side to side and front to back.
