hey is my zetec liekly to break the diff? It will break the tires, 215 60, loose when dropping in 2nd and if I really try 3rd. What exactly breaks in these things? Does it generally destroy the tranny in the process? In my neon I blew the tranny up after hard driving since the diff pin slid out and let the spider gears go.
