with stock axles you can only go up to 4.88 which is a tad short for running 35s (4.88 and 33s will get your final ratio same as stock).

If you have dana 44s front and rear you may consider 5.13.

For 35's, no less then 5.38's.  This means doing two axle swaps.  You should have at least replaced the rear with a Dana 44 or the like.

You in Hawaii?  Where'd you go Maui Offroad?  If you had a 4.0L then 4.56's would be OK but not with a 2.5L.  You can go with 4.56's but it's really too high.  If you're driving on road all the time then it won't matter as much but if you're going through passes like Likelike Hwy or even the hill heading past Aloha Stadium to Pearlridge, it's gonna suck.  Even the slope from H1 to Millilani sucks as it's all open to wind and it's a LONG steep hill.

If you're running a manual then there is no reason not to go with 4.88's.  Although, I'd highly consider swapping axles to get even lower gearing.  If you're still open diffs then you should be OK with 35's.  Install a locker and you'll probably be spitting out axles.

like everyone said, 5.13 or 5.38 is the way to go for 35s - the only problem is that with stock axles you can only go up to 4.88 so you don't have a choice
