welcome to the forum... first i would say you need to know what size gears you have now. which you can usually find on the door sticker. for 33's i would say you should have at least 4.10, also if its 4x4 youll need to match the front diff as well. as for how hard to change gears its a bit of labor, need to pull the rear wheels and axles rear drive shaft races and bearings shims and side gears, the carrier itself and have everything set up (ie the new ring, carrier bearings pressed on, the pinion bearing pressed) and the same with the front but i think that diff has to be out of the car to do it.

Welcome to the forum, what's your axle code or gearing in your Ex? I'm actually running 3.55 gearing on 33's on my 96 Ex and not bad for a daily driver and 4.56's in my 94 with 33's. Gearing depends on your intentions...

The '01 Sport came with either 3.73 or 4.10 stock. But like every one else has said check it first. I run 285/75/16 = 33" with 3.73 as a DD, it does okay.
