limited slip differential oil?

I replaced my passenger side axle this weekend after reading the how-to's
on here. I used to be a member of the ShopForum over 10 years ago and I remember reading that if your diff cover was fined there was a good chance you had a limited slip differential. well mine is finned and the inside looks like a limited slip differential "I know it's kind of wasted on a 240d" so the Question is what kind of differential oil do I use ?

That looks like an open diff to me, all you have in there are 4 spiders and the spider locking shaft. Use a GL5 rated gear oil, your manual should list the viscosity, I can't remember it off the top of my head.

It does look like a regular diff. To tell for sure, jack up both sides. Then turn the wheel on one side, while observing the opposite wheel. If that wheel turns in the same direction, it's limited slip. If it turns in the opposite direction, it's open.

That is 100% an open differential. Not a limited-slip.

A rear cover with fins possibly being an LSD is BS, sorry.... many diffs have those fins (couldn't tell you exactly which ratios/chassis had them, I know a '77 280 has one...)

None of my regular parts suppliers seem to carry any drive axles for these anymore .

You can get a really high quality rebuilt axle from cvj in Denver. I also recall peachparts and Auto Haus also have chinese rebuilts that are annular. No need to crack the differential to replace those!
