It's ok with a 93-95 249, but with a 96-98 249 or any other t-case, the driveshafts are locked in 4lo, and bad stuff will happen. As towmaster said, "don't do it".

You run it on dry pavement AS LONG AS you do NOT make ANY turns. Soooooooo.........don't do it...

Actual pavement bad idea. But areas like Moab I see guys run lockers in 4LO most of the day (very slowly) and it seems to work

4 lo on pavement on any other case besides the 93-95 249's is bad because the case locks the front and rear outputs, in a turn, the front wheels need to spin faster than the rears, the case will not allow it and stuff starts to bind and break. the reason you can use it off road is that when you take a turn, the rear tires just spin on the dirt or whatever. pavement does not allow the tires to spin to keep up with the front

I did indeed forget the exception there, that is my mistake. But I will still suggest even in those not to do it, just as a general practice so it isn't forgotten. I think the only time someone would need 4lo on pavement is for the gear reduction to pull something very heavy that the vehicle can't handle in 2hi/4hi/4PT/etc. That said, that's a terrible idea for several reasons. One, its obivously too much for the vehicle to handle, use something designed for it, and you couldnt go more than what...20mph? Even just to pull a big trailer across a parking lot is a bad idea, becuase it's pavement. I got lazy once and didn't feel like getting the truck so threw the ZJ in 4lo to pull my boat across the yard. I was on dirt so that was ok, but it was still a DUMB idea, because the Jeep sin't designed for that. followin us?

As long as you don't turn or go over 25mph it wouldn't hurt anything.

only time 4lo should be used on pavement is pulling a boat out of a launch.

I would think on a muddy boat launch you would be just fine, the wet cement would be slippery enough I would think, just disengage asap. But then again, that 5.9 should be fine as long as the tongue on your trailer is long enough.

its designed to run on pavement. thats why there are separate options 4ft is for on road, and 4pt HI is for off road.
