how to change differnetial oil (W124)

Ok guys,

I've read through the archives and amassed a bunch of info I want to confirm. I've never change the diff oil in any of my Benz's and want to start (usually my mech. takes care of it.). From what I've gathered, this is not any more difficult than changing the motor oil.

1.) remove drain plug (check that you can remove fill-plug first
2.) drain fliud,
3.) replace drain plug
4.) refill with fresh fliud

One question is - is it beneficial to get the oil hot like with motor-oil changes? How much driving required to do so? What is the recommend intervals for changing diff oil?

Also, any other caveats or tools to make this go as smooth as possible?
