The main thing is the Wrangler's 4x4 system is what is known as a "part-time" 4x4 system and should never be used on pavement. Not even when the pavement is wet from rain. When on pavement, dry or wet, it will create jerky steering pulling, bucking, all kinds of problems and as such, is designed for offroad use only... or when the roads are completely covered in snow or ice. It can't even be used on wet roads when it is raining because there is too much traction on wet roads for a part-time 4x4 system.
Use your 4x4 only when offroad or, perhaps, if the roads are completely (!) covered in snow or ice. You can't even use it when the road have patches of snow or ice.
Only full-time 4x4 system slike you can get on the Liberty or Grand Cherokee can be used on paved roads.
