4WD hi question

I switched to 4wd hi to deal with the puddles and slick roads and everything is great. My question comes when I am maneuvering slowly through parking lots it feels like I'm ice skating. What up wit dat?

Neither 4Hi nor 4Lo were designed with paved roads in mind. Both are "part-time" 4x4 systems meant for offroad use or on roads covered in snow or ice. Wet roads like you were driving on have too much traction which caused the feeling you noticed... the front and rear tires were "fighting" each other during your turns.

The reason is that both 4x4 modes completely lock-step the front and rear axles together so the tires at the front and rear are forced to turn at the same rpms... bad during turns because the front tires need to turn faster than the rear tires do during a turn.

Leave 4x4 for offroad or roads completely covered in snow or ice. Only full-time 4x4 systems like are available in Cherokees, Liberties, Grand Cherokees, etc. are suitable for use anytime anywhere including wet roads. A full-time 4x4 system allows for differentiation (different rpms) between the front and rear axles.

Thanks for the knowledge. I had a Cherokee before the wranlger so I guess I was used to that. I bought my TJ used, so I didn't get the benefit of an owners manual. I just follow the instructions on the visor.
