    Hey, recently picked up a Cherokee and am wonderin whether or not is it possible to switch from 2WD to 4WD while driving.. I am hesitant to try b/c i want to fk the ride up. I know you can do it while parked [obviously] but am uncertain whether or not you can drive in 2wd and then while still moving shift to neutral and then switch to 4wd.... Anyone?

    hah, i wish i could go off roading... but i'm too big of a newb with that stuff. My XJ is stock and I want to keep it in decent shape for a long while... therefore no offroading for her, unfortunately... :(

    well one general rule is that you should only use 4lo when you are really stuck or climbing something, keep the speed under 15. And then use 4hi whenever you need to keep from slippin like on slipery roads or when just offroading in general.

    Not exactly, you would end up going from low to high gear a million times if you're wheeling for a few days. I only take it out of 4Low if I have a long distance to drive on a flat surface like a dirt road and I'll drop it in 2WD if I hit pavement.

    In a Jeep such as a Wrangler or a 4WD Cherokee there's a transfer case mated to the rear of the transmission which is then connected to the front and rear diffs with drive shafts. When the t-case is in 2WD it acts as a pass through which means the input shaft and rear output shaft spin at the same speed. In 4High the front driveshaft output is engaged but it's still a 1:1 ratio so both the front and rear driveshafts are spun at the same speed as the t-case input shaft. In 4Low the t-case then acts as a gear box and it increases the gearing by a set amount. This increased gearing gives you a higher crawl ratio which in turn gives you more climbing power and the ability to crawl over obstacles without stalling the motor. The higher the ratio in the t-case the higher the gearing and the slower the wheels will actually turn.

    So to swtich into 4lo or hi.. do you drop it into neutral first?

    I've just bought an 89 Cherokee limited, i think it has 4 settings on the 4X4 shifter. 2wd, 4wd fulltime, 4lo, and 4hi (i think).
