4L10 would mean that it came from the factory with a limited slip diff and 4.10:1 gear ratio (Ford never offered a locker).

Are you thinking it's not the factory limited slip? We'd need a picture to help you out any more than that.

it looks like the clutches are on the end of the axles instead of a center section

The clutches can be restacked to provide a tighter lockup just like a Ford 8.8

It's not the limited slip......the yoke that slides into the driveshaft has been known to go "dry" and cause this issue. Pull it apart and regrease it.
