Last night a SOB in a SUV ( "I'm sick of these SOBs/ Driving these SUVs/ Trying to run over me when I'm in my beat-up car,", funny blues sone you should listen to it) nearly ran me off the road while changing lanes talking on the phone, while speeding. Couldn't even be bothered to stop and see if I was ok. Rashed up my rims which survived 30years nary a scratch. I had locked up the front end and contacted the curb before I let off the brakes.

Needless to say I am back on the hunt for installing ABS. Coupled with a crappy rubber boot on my non OE/M balljoints and torn up spindles, this will make for a nice upgrade. No I know in ABS models the back end has a sensor in the diff. Is this true on all models? In order to install ABS I would need either a diff with this sensor or some way to recreate or bypass the signal. Ideas?

Alternatively I could get an arduino board to control the ABS but I'd rather go OE if possible.

You can always go aftermarket. I'm sure there are lots of hot-rod restorers that want/need ABS for their ancient machines.

I'll help you research a bit later tonight.

Aftermarket ain't cheap. There are have a dozen or more ABS equipped 126/201/124 in the yard right now and that is cheap.

Anyone have 201/124/126 manual covering ABS?

I do.

This site has all of the 124 manuals (on the left side CD1 and CD2).

PM me if you want the W201 Manual.

On a subsequent notice. Would you happen to know the part numbers for non-abs Mercedes Splitter/Balancer things, I want to delete the abs off my W201. I've driven a non-abs W201 before but I don't own it anymore to own on the parts.

Or More Specifically.

I'm new to forum. I have the factory cds manual from 114 to the 126 chassis,

I think they also offered ABS as an option on the w116.

Service manual link.

you want ABS on the 123 right ?
it was an option the last year ..

there is a 123 at my local boneyard with ABS..
all the parts are there, and it does have the sensor in the diff,
so you would have to swap the center section in.

LSD diff by any chance?

Not in a W123

When I swapped rear ends from 3.07 to 2.88, I used a 1985 300SD rear end that had been equipped with diff mounted ABS. The rear end was identical in all other dimensions and fit the 123 no problem, but the sensor was on the passenger front of the housing reading off a speed sensor on the pinion shaft. I dont imagine that would be too easy to swap. Maybe you could find one of these rear ends in a junkyard.

Ironically, I removed the sensor and plugged the hole.

there is an 1985 280e at my upull-it here in Albuquerque that has ABS on it

Ooooooooooooo. Can you take pics?

Its been a while since this discussion was active, but I was working on a mid 90s chevy truck the other day, which did not have ABS, but we accidentally ordered ABS half shafts, so we knocked the rings off instead of dickering with the parts delivery guy.
Why not source one of these extra rings and finagle it onto the inner drum of a MB axle, then mount a hall effect sensor on the outside of the diff itself?

I dont really think there is a need for the diff sensor, all that is needed is replacing the front spindles and hubs and of course the ABS controller/pump. I mean locking the rear isn't that big of a deal IMO.

It needs the rear to know the speed difference from the front to back. If you only have sensors on the front and both fronts lock up, it won't know they've locked.

Adding a tone ring to an axle or the driveshaft would be less of a challenge.

I dont get how that is. Its just a rotary sensor. I guess it needs to know that you are actually moving, you could probably use the cruise control sensor for that.

hey winmutt,

there is an '85 280CE local to me with ABS. it must have been a grey market because it even has the trunk triangle and SLS on the rear axle..

if you want i'd be glad to go take some pics and get part numbers for you. im sure the owner would not mind.

Get the struts in any case, they are different from the wagon and could fetch a pretty penny.
