The pinion nut in the middle of the flange? That shouldn't be working loose, it's supposed to have loctite on it and be a lock nut I believe... That's not normal, I've been here long enough to notice some trends, and been abusing my Ranger long enough to not have a problem (turbo engine in for like 6 years now, lifted and locked for 5)

When you run out of oil and burn the pinion bearings then your seal will leak and the NUT will loosen. So check your oil and don't reuse old oil.

Also, you cannot retighten the pinion nut correctly without using a new crush sleeve and checking preload.
