SLK320 Rear Differential Fluid Capacity
What is the fluid capacity of the rear differential, and what is the weight/viscosity of it (I believe it is 75W/90). I have a 2001 SLK320 with an automatic. 
Thanks!

Here's a link to the writeup I did for the 32.

The 230 and 320 are essentially the same. The factory fill is 80W-90, but I used Mobil 1 Synthetic 75W-90.
I think the capacity of the 230/320 is the same as the 32. It's definitely not going to be more than 2 quarts, but if it's less than 2 quarts, you could always take the extra quart back. The biggest problem is going to be finding a 14mm hex bit/wrench to remove the fill plug and drain plug.
