Is one tube enough or front and rear differentials of Permatex 81182 Gear Oil RTV Gasket Maker, 3 oz?

More than likely but it also depend upon the size of the differential housing(s) and how you apply it. If you apply a 1/8" or 3/16" wide bead, probably so!

Can it be used in transmission pan too ? Or is just for diffs and transfer case ?

It is good for any kind of oil, diff, transmission or engine.

Can I use it for mustang gt?

Yes, it is rated for Mustang GT

I have a small drip on a differential stud.. on a Tacoma will this be good to use as a dressing over the hex washer nut to stop the drip??

First off i would remove the nut then spray that area with brake cleaner. Then let dry then apply the sealer around the stud then use a flat washer followed by a lockwasher then the nut and tighten. Give the sealant a chance to cure. Good to Go.
