I want it in my w123, these one wheeled burnouts are lame, and more than once I've almost gotten stuck turning right out in the country if the rear passenger tire isn't on the asphalt and just spins in the dirt. That being said, what can I do? I know there was an uber rare lsd option for the cars that I'm sure I'll never see, so what are these funky lsd things I've seen added to the differential in other threads? Or am I just gonna have to deal with open diff?

In the works: A/W IC, adjust pump, turbo rebuild (w/60 trim comp wheel)

If you weld it be sure to use solid core wire with gas, otherwise the spatter will kill your operational gears

its strange that you americans havent got LSD in your differentials :/ you value electric windows, leather and AC while the europeas only value LSD... the differential, not the happy drug.

both 3.27, 3.06, 2.82, 2.65, 2.47 and 2.24 exists as LSD over hear. althou they are expensive if you isnt buying a car, they isnt anywhere near as rare as over the pond...

i think welded diffs are a nightmare, to go from welded to LSD is as night and day, damn it feels good to be able to make quick turns at slow speed without the tires sqeeking and draging like hell.

It would probably be easier to retrofit something different. I have an 06 GTO diff that I aquired a while back, its got kinda similar mounts but with a little fab work would fit. Id just have to frankenstein the gto and merc axles together. But that would just be a machined sleeve that I would weld between the two (we aint talkin big HP here LOL) and then get them balanced.
You could probably use about anything you could find at a junkyard. The Ford diffs are easy to find and 20 different types of LSDs are available from Summit for cheap.
Or you could just weld the diff. But I think my 240 would just stall turning corners Smile

Of course! Smile Power steering had to be ticked right until '82 I think. But it's rarely NOT been ticked, though. And isn't that much nicer to drive, the steering's still "dull" and unresponsive. Neutral scrub radius saying hello Wink

al w126/w116 where those rearends origin probably had powersteering, havent stumbled upon any S-klass without P-S, even the low-budget 280SE.


havent stumbled upon any w123s with manualsteering either, althou i might have heard of some, the w115 thou are more common without powersteering.

there is one major issue with manual stearing, you have to turn the stearingwheel like a madman due to gearing, and you still have to fight with the stearingwheel while standing still on asfalt, especially if pressing the breaks.

(it is a tad more direct to the road, and as long as you are moving, not heavy at al. But on snow, to drift, you better be ready for some quick spinning of the steeringwheel)

a friend has a r107 with the 560 engine and dual turbos, due to large turbos and piping, he had to remove the steeringassist-pump, roling the quite large r107, with the powersteering-gearratio but without assist, and 730whp... Tongue

It appears to simply press against the spider gears creating additional friction once they begin to rotate at different speeds. This should be an additive lockup: it will take, for example, 30nm of force to rotate one axle independent of another under all conditions. Compare to the LSD's that came in mercedes that have a multiplicative lockup: The more force put in the carrier by the pinion gear, the harder the spider gears are pressed into the LSD clutches, giving ~30% lockup. In other words, those spring things are turds.

They just add preload to the side gears in effect making it "better" than an open diff. Without machining the gears for clutch discs they probably end up just destroying the gears and housing over time. I also dont see a way to get the axle c-clips back in.
Might as well just weld it Smile

If you guys want to really do this find the appropriate 210mm differential to fit into a w123 from another car like Winmutt suggested and put the Quaife in it. This is what I am going to do with my wagon eventually. No question. The stock lsd units suck and the cost to rebuild one in parts is pretty high. I think that any early w116 and up 210mm differentials with gear ratios from 2.7- up to 3.07 are compatible with the QDF5v. I would have to go back and double check all the epc cross reference numbers. This is how I ended up using this unit in a w124 is because it was listed for the 500slc. The carrier is the same for around 20 years until the late 90's. I have done many installs and driven hard with these units. They are worth every penny and as already stated do not wear out and have a lifetime warranty. Not that you are going to need it. They used standard gear oil and the lock up is variable from 0-100%.

I would have to go back and double check all the epc cross reference numbers. This is how I ended up using this unit in a w124 is because it was listed for the 500slc. The carrier is the same for around 20 years until the late 90's. I have done many installs and driven hard with these units. They are worth every penny and as already stated do not wear out and have a lifetime warranty. Not that you are going to need it. They used standard gear oil and the lock up is variable from 0-100%.

Does Quaife sell LSD kits or do you have to buy the whole diff?

BTW, I believe that the 6.9 is the only W116 to have come with limited-slip. Not terribly easy to find -- I have dreams of finding a low-mileage rustbucket 6.9 that I can rob the diff out of and make $1000 on by selling the engine Tongue.

Also, is there a way to tell whether or not a diff (say, in a 560) is LSD without blowing it open?

If you can't afford or find an LSD I'm pretty sure you can get solid spools that can fit in your diff, it'd only cost a couple of hundred & it saves you from potentially destroying an otherwise decent diff.

From what I've seen they only sell the diff centres, but then you're looking at about $1500 even for that, Quaife stuff doesn't seem to have very high recommended power ratings for what you pay.

Quaife does not have a power limit per say. They will however not warranty damage from other parts breaking around the unit, ie half shaft stubs and ring and pinion. Which you will break long before their unit. I would like to see the car that has enough tire and enough torque at launch to break one of these on here with upgraded axles.

Why not install a diff from another car? There should be plenty of jap cars with LSD's or aftermarket units available. The hard part is finding something with the right ratio. I know Nissan diffs are out of the question as theyre quite high ratio compared to a Merc diff.

If you find something with a ratio of between 2.5-3.0 then do let me know!

Its going to be pretty hard. The easiest option I can see would be a 2.79 from a BMW e36.

Im more tempted to go down the custom route and get some gears made up. This would enable me to go with any diff I want and have exactly the ratio I want. It shouldnt be too expensive either, there are only 2 gears that need to be made.

Wow I can't believe all of the replies talking about welding the gears up. All I have to say is that this would be a silly idea on a street driven car, not to mention an IRS equipped one. It is hard enough on a solid axle to turn and maneuver with a spool, but on an IRS car it is brutal on the half shafts and rzeppa (cv) joints. Just setting up an IRS limited slip too tight is difficult on parts, and the diff still has slip built in (100 ft lbs or more). Get yourself an LSD and do it right.
