This kind of leads to what one of the member siad near the start of the Thread that the Seal often leaks if there is a problem with the Bearing; and, that would also be a resonable explaination as to why the nut was loose.
However, the problem is what is he to do now?
If he installs the Seal he will need something to Torque the nut to.
Or if he decides not to mess withit he had indicated he was open to getting a used Differential.

what he needs to do now is to preload the bearings to a certain rotating torque as mentioned in the fsm.
For example, using an impact (would not suggest but it works) run the nut down until you have no endplay on the pinion.
Next measure your rotating torque, you should probibally have 5-10 inch pounds of rotating torque required to turn it, if you dont have that then you need to run the nut down some more.
By the way this is the reason that your seal was leaking, since the tapered bearings allowed the shaft to wobble when the nut came loose. so replaced the seal, use sealant on the splines and then tighten it to the FSM specified rotating torque.
Also, the nut could be torqued to 100foot pounds and still not be at the correct pre-load for the tapered roller bearings so do not try to torque that nut down, you must go by rotating torque and the axles must be disconnected in order to measure it.
