Transfercase: 4hi works nothing else.

When in neutral i engage 4 hi and it engages, and the dash light turns on. But it seems like I cant get it to go into 4 low. I try to wiggle/force it and it just stops. I dont have a repair manual on me right now but where should I start trouble shooting this? The jeep makes no irregular sounds when in 4 hi, but it turns like a *****. Is that a indication that the PO may of had a locker installed?

Ran out and tried it. With some solid kidney punches to the shifter i got it to go in. Now it works like a charm. Im assuming the PO used this rig as a pavement pounder and never needed 4 lo, but my first time wheeling i woulda killed for it lol

Hey what are the symptoms of a locked front end? When the truck is in 4 wheeler and i try to turn at all it jerks and wants to go straight, i dont know hard to describe but its not line any other 4x4 ive driven.

The np231 transfer case is a part-time transfer case. When it's in 4wd, the two driveshafts are locked together at the same speed. This causes hopping when turning because your front wheels aren't turning at the same speed as the rear. This is also why you should avoid using 4wd on high traction surfaces.
