I recently changed the rear subframe ( rust) from my 240D manual to a subframe from a 300D. I left the 300D differential ( 1983) in place in the hope to get a better fuel mileage.
In my opinion the car is a lot more fun to drive. Yes here in the hills of PA I have to get back to second gear sometimes but anticipating traffic and road makes it a lot more fun. In the city the longer gears are much better.
Mileage has gone up from 28-30mpg to 34-35mpg, kind of amazing because I almost drive full throttle all the time.

You've been asking this question for a while. Kind of shocked you haven't found one yet. They frequently show up in my local yards.


That's an ultra rare unit that will fit a first gen w126. Where or what year/model did you pull this.

I believe it came from an '85 500 SEL, but I'm not certain. I didn't pull it........it was sent to me.

Didn't the 81-85 500 series w126's use the 2.47 diffs? There is at least one at the winston pick and pull. I had my eyes on its rear subframe.

with all the talk about rebooting half shafts around here, I at least need to pull that diff and shafts. Then send the shafts to John for rebooting.

Now, am I to understand that you 'reboot' the half shafts using the outboard section of the 116 shaft/outer CV joint and the inboard 126 CV Joint when adapting this 126 differential into a 116????

You went from a 3.69 differential to a 3.07. This means your speedometer and odometer are now off by a fairly significant amount. Which is why your mileage "improved" (in reality it likely has not). As your speedo and odo are now reading several mph slow.

Interesting. If you get a chance, can you snap a pic of the internals. I have never seen a First Gen 2.47 LSD diff before... even in pictures.
I've seen 2.24, 2.65, 3.27 and second Gen 2.47 LSD in person.


That is surprising, since the 2.47 is easily found on 1981-1985 gasser w126's you should have a favorable probability of finding one as opposed to the one year only 1985 2.88. I probably seen a dozen or so 2.47's in the past year and zero 2.88's in my local yards.

That is what prompted our entire swap. We found the good condition axles/diff in the euro at the junk yard....bought the whole thing as one giant piece for about $110. We took it all apart, rebooted the axles from the 500, and trashed all the original stuff from the car (axles clunking & grinding, diff had a TON of play and metal shavings coming out of it) We swapped in the 2.47 diff without much trouble, and the axles it came with minus the balancing weights. So far so good....it has covered about 8-10k so far. The diff whines a bit....but it is generally smooth, and the axles have been perfect. The inside of the diff looked fine when we checked it, no metal shavings or signs of wear, and the oil was new, so the owner must have taken good care of the car.

Well - I have found the MB diesel "easter egg"
