Pinion seal leak and loose pinion nut?

I noticed my pinion seal leaking and tore it down to replace the seal, but when I went to loosen the pinion nut it took really no force at all to get the nut turning. From everything I have read this thing is a ***** to get off and so I am wondering if the nut being loose is what is causing the leak. I have no reference point to tighten the nut other than the torque recommendations. Any thoughts? I would prefer not to have to replace the seal if I don't have to.
 

Also for you AMC 20 rear end folks how many threads deep is your nut tightened if you remember. I only had three threads showing out the end....
 
Went ahead and replaced the seal and will torque it down to 180ft lb and just go with it... Didn't replace the crush sleeve so hopefully I don't have to redo anything.
