Jeep Wrangler, 2002, 2.5l - Something strange happened while driving it in 4WD?

Question

I would appreciate if someone can help me. During my regular drive my transitions is in 2WD. Today, during snow, I switch from 2WD to 4WD (of course I was park during switching) and when I started my drive, I realize that something is wrong. While I was driving forward everything was normal. But when I turn first left then right I feel something similar that I use my break. Jeep was started to jump up and down, as I sad before, like I was pressing break pedal during my drive. At first moment I thought that something is wrong with steerwheel or my tires but there was nothing wrong with it. When I switch to 2WD again, everything was normal. Does anyone has any idea what happened with my Jeep today? Note: 20 days ago, I was driving in position 4WD normal, without any problems.
Thanks.

Answer 1

The drivetrain was binding up when you turned. That is why everybody and everything says to not drive in 4wd while on dry ground. I'm not saying that the road wasn't slick, but you could have been on a spot where you got good traction, and it bound up slightly.

Nothing is wrong with your jeep. In 4wd, you should expect to have a 'heavy' steering wheel, it may feel like something is dragging like your applying the brakes slightly while turning, and even a slight bucking sensation while turning (more so during a tight turn). You aren't causing your jeep any harm, these are just characteristics on being locked in 4wd.

Answer 2

Your jeep isn't designed to be used on dry pavement in 4WD. What happened was your jeep being in 4WD the tires that were on the outside of the turn were trying to turn faster than the ones on the inside of the turn causing the vehicle to "hop". This is normal in a 4WD vehicle on ground that is dry and the wheels aren't able to slip enough to compensate for the different speeds.

Running your vehicle in 4WD on dry pavement is bad for the vehicle
