Ford limited slip clutches??????

[gijohn40]

So about a month ago I bought a 01 Ford F250 psd and that night I took to looking at all the fluids... the rear diff had a big solid grease ball where the fill plug was so I figured I would change the oil today and when I got the cover off I looked at the diff and it looks like it is a limited slip from the factory... I took a few pic and would love to have someone with a little more experience confirm what I see...

So post up what you think... the second pic has what looks like a shit load of washers which I think are clutch discs...

Yup, looks like an LSD to me.

Just make sure you put the right fluid back in.
