that is what was just discussed

 

your right , that is what was being discussed, just not clearly what i was saying is that if you are in a mustang doing a one wheel burnout you have an open differential. if you had a limited slip differential it would apply torgue to the non-spinning wheel stopping the spinning and helping you get going forward.if you had a locking differential you would get even amounts of torgue to both wheels all the time so either they both don't spin or they both spin. that should answer your question on why the wheel with the least amount of traction spins? (you have an open differential) also i was answering the first person in this post on which axle he might have. don't believe everyone when they say 44hd without checking for your self . ford put d60's in 78 f-250 full time 4wd's.there are plenty of posts on this website to tell you which axle you have. the best way to tell what t-case you have is to get under the truck and look! np203 are a big cast iron case with an aluminum tail housing and the shifter linkage hooks to a lever on the side of the t-case.a 205 is a smaller cast iron case with the shifter linkage connecting to a steel plate between two steel shafts going into the front of the t-case. the 205 is shorter than the 203 so you would have to lengthen the rear drive shaft to swap them out. i hope this clears it up.
