also wanted to add, the trannies suck... haha... ford never had good trannies, ever, but there are a coupel things you can do to them to fix their issues and make them pretty reliable
the 91-94s mainly use auto locking hubs and a electric shift tcase, some did have manuals on both accounts though. when i had my 94, i swapped to the manual hubs, the autohubs may or may not work and are unpredictable, i never had a problem with my eshift tcase
