My Jeep Hates 4h

Well as the title says my jeep absolutly hates 4h. when out wheeling i can make it further up a steep hill in 2h then i can 4h. it just dies out on me and sounds like a diesel, it feels as if im trying to take off in 2nd gear or something, the easiest way for me to get up a hill is to get speed in 2h, or 2nd gear in 4lo but 4 high wont do anythin. any suggestions? and to let you know this was with stock tires as my jeep has not been off road since gettin new rubber. and is in the shop now gettin gears. thanks

4Lo is the way. I only run 4Hi if I'm driving on treacherous roads (offroad or in snow). As soon as I get to something more severe than a dirt road I hit 4Lo.

If you are hill climbing in 4Hi - turn off the ESP. I have found this makes a big difference - not sure why, but it does.

^Agreed. When it dies down like that, is your ESP light coming on?
Also, you'll need more revs to drive all 4 wheels vs. being in 2Hi. Is yours a 6-speed or a manual? Mark W.
