gears?
 

OK so my college semester is almost over which means back to work and more goodies for the truck!.... but i have added another one to my list, all winter long i would get stuck on stupid ice or slush because my truck is a one wheel wonder....im thinking its the 3.54.....should i replace everything if so my buddy has i think 3.55 or 3.73 i cant remember, or should i just put lockers in it? im not much of a mechanic so any advice would be great thanks guys!

Lockers.....Unless it a 2wd than it's whatevers cheaper

gears are fine just put something in the rear to help you out.
