I've been reading up on the web about self locking diffs that were fitted as an option on 123s. My 300TD clunks in reverse and is a bit sloppy and needs replacement. Seen as I am building up a semi off road Diesel touring machine I wouldn't mind something self locking or limited slip in the back to go with higher springs.
Has anyone heard about or know of these diffs? There is nothing in my technical books and the tags on the body don't indicate what diff or axle is in the car.


I was thinking of getting a G wagon chassis and popping the S123 body on it for the ultimate off road experience but they are as rare as hens teeth in AUS.

Are there any aftermarket manufacturers like Eaton or other auto locker makers who make stuff for these models?
Could the diff be made or derived from Borg Warner? Like so many others they could be cross matched.

The gear ratio for the differential, is on the lower left side of the Diff.
Clean off the corner on the Diff. housing, not the cover. It is stamped
in the metal.

Don`t believe the W123 has a limited slip, locking rear end. there might be some
in markets out side of the U.S.

Check your driveline, could be your flex disc or center support bearing.

Drive line has been checked as I had the motor, transmission and drive shaft out to the rear flex plate. There is definitely a clunking sound in reverse. Could be the shoes dragging, maybe. The plan is the pull out the complete rear end for a total rebuild/rebush.
I'm sure that there was an option on these for a limited slip or auto locking diff. I wonder what would fit in. A Detroit TrueTrac would be nice.

The 123 never was offered with a limited slip. A limited slip from a 190 sixteen valve can be cannabalized and the limited slip parts can be put into the 123 diff but a spacer is reauired on the ring gear to get the proper clearance.

Its not too bad if you know someone who can work on a diff.

There is a 16V 190 in the yards here- is it worth it to pull the diff and what other parts to go with it? (engine/tranny is gone)
Thanks

It's all in the eye of the beholder! Somebody is bound to need it eventually.
But if it were me and priced to where it doesn't matter if I screwed it up, I would get that 3.27 and try to make me a w123 3.07/2.88 version of it. Just for kicks.
