Weird steering issue while in 4WD
 
When driving in 4WD around tight turns there is some weird wobble in the steering. Do I need a stabilizer bar? This is at slow speeds just making a turn. It doesn't happen in 2WD. Is this normal for the JKU?

Well, it's normal if you're using 4wd on dry pavement, where you're NOT supposed to be using 4wd. Some hop is normal from the front end in 4wd off-road as well. There are some fancy technical terms and explanations I can lay on you, but I'll save everyone the boredom, lol. Your Jeep already has a stabilizer bar.

my assumption would be [B]because[B] you're in 4wd...You've got four tires all trying to push you around and when you crank the wheel you've got your front end trying to go one direction (left or right) and your rear end trying to go a different (straight) so it causes you jeep to sort of "jump"...you will probably notice it mostly on pavement....that's my theory.

There was some nasty thunder storms here in NY over the weekend. Thought I'd give the 4WD a go for the first time while driving in the storm. Thanks for the info.

^^What they said. It's not weird. It's a consequence of the design of a part-time real 4WD system like the Jeep's, not some weak AWD system. Do not drive in 4WD on dry or even wet pavement. In fact, if you're on pavement at all and have traction in 2WD, don't be in 4WD. Even with snow or light offroading, if you can do it in 2WD, keep it in 2WD. The only time you should be in 4WD is when 2WD handles poorly due to low traction. Follow that rule and you'll be fine. :thumb:

Cool, thanks for the info everyone! Just glad it's not a defect or something.

When a vehicle turns, each wheel rotates on a different radius to the turning circle, thus traveling at different distances and speeds. If the vehicle's front and rear axles are locked together and are turning on dry surfaces, the difference in wheel speed sometimes results in driveline binding that is released with a “bang” or vehicle “shudder” when one of the tires loses traction.

Doing it often can have some very bad consequences.
