Sorry for the thread jack, but convo is of interest. I just picked up a 97 4x4 a couple of days ago, never owned a 4x4 before, and I forgot to test to see if 4x4 mode worked, oops! So what's the final verdict here, 4 Hi or 4 Lo for a short distance on dry pavement to test?

4hi is save to drive on pavement. 4low is not. I honestly dont even know what the point is to have 4low.

Have you ever tried pulling anything in 4hi....must not have because 4hi can not hold a candle to what you can do in 4lo

gustrider4

really like what.

I always thought the reason you shouldn't do 4x4 on pavement had to do with the front differential being totally locked (not opened) and thus the geometry in a turn would make the ties "chirp" and put stress on the internal components of the 4x4 system. Is this not the case?

On these trucks, the front isn't locked by any means. Its just a conventional differential. The hopping is from "push/pull" action of the front and back fighting each other when you try to steer

SR2K

Um, no, you're wrong. The tansfercase locks the two axles together regardless of hi vs lo, the only difference is it adds in a reduction gear in low to give you more torque.

Thus making driving on pavement in 4 low worst

Moral of the story is, avoid using 4x4 hi or lo on dry pavement if possible.
