Boot? as in security boot?

It might just be that the posi isn't sticking together well. Is it used or new? Under high friction differences the torque of the engine will overcome the posi, but we need more details... Used or new? boot? which auburn?

Most of the Auburn Posi Diffs use metal cones for friction instead of friction clutch plates like the Eaton Posi. I don't think the cone type Auburns require a posi additive. I may be wrong. I'm sure someone on here knows for sure.
The cones wear against the diff case for friction, once the diff case is past the wear limit it's done.

Being that the posi unit is used...there is no telling. Unless you knew the history of the unit you should have gone through it before intalling it IMO.
