4hi is for riding down a gravel road and going over 25 mph in 4wd(loose dirt or ice only)

4lo changes the gearing in your transmission as well as engaging the front axle. Do not go over 25 mph and only use for climbing or getting unstuck. If i am on the trails i use 4lo the whole time and creep. If you re going down a steep hill and want to save your brakes, drop it into 1-2 while 4lo is engaged and your tranny will do the braking for you and "walk" you down the hill.

Always come to a complete stop, put jeep in neutral, shift into/out of 4wd, put jeep back in gear and drive. Neer use 4wd on pavement unless its icy and you are going slow.

Sell me the jeep when you realize you are in over yer head. Been wanting another wrangler.
