Can't shift into 4 LO

I'm new to the forum. Long time Cherokee(s) owner and am now in process of buying a 2003 Wrangler, my first. I test drove it this morning. Two problems: 1) I think maybe U-joint problem since when engage 4-wheel HI then turn the wheel in both directions while in motion, I get a clicking sound when nearing the max turning radius. 2) cannot shift into 4-LO; the lever will not move to the right. . . xfer case prob? My procedure for shifting a Commandtrac is: (I usually stop) wheels straight, xmsn neutral, pull in either HI or LO then move out. Any tips would be appreciated. If these problems are somewhere in the forum that I overlooked, I appologize. ghs.

Mine shifts like butter if I am rolling about 3-4 mph in neutral, just pull straight up and it pops right in. If I'm stopped it takes some work.

The clicking could just be the tires skipping over the ground or "hopping" when you turn. What type of terrain were you on when you tested it. As far as 4wd lo, make sure you are moving in a straight line under 3mph with all wheels going the same speed. If it doesn't move it could be a problem with your linkage from the stick to the transfercase. If neither of those help, then it leads me to believe its a transfer case problem

does the jeep have a lift on it? if so, and it has the TC drop on it, I would lean towards the linkage. i had the same problem with mine. either spend the money for a new bracket, or relocate for free. not sure about the clicking...could be a few things.

I will walk you through mine as an example.

The PO had a 4" sl instaled that came with a tc drop kit on it (2 - 1" steel bars placed in between the skid plate and frame) This binds the crappy linkage from the factory because of the new angle and sometimes makes it hard to shift into 4lo or stay in it. To remedy this, I did the following:

-Unscrew the four bolts holding on the bracket for the linkage. bolts are inside the cab and bracket is underneath.

-Remove the bracket from underneath paying close attention as to how the linkage is put together down there.

-Take that bracket that the four bolts screw through into the cab and line it up with the original holes. Now slide it down roughly 1" and mark for new holes.

-Drill out those holes, grab some longer bolts that you probably have laying around in a bin and re-install everything. Since the area that the holes were drilled has a bit more of an angle than the bracket used to sit on, I put a few extra washers on the bottom two to kind of compensate.

Your shifting problem is fixed. 4-lo all day long. If you feel the need, you could always weld some tabs into the old bolt holes and paint or something. I didn't just because I was planning on doing what I just got done doing....installing a SYE and taking out that darn drop kit.

Thanks to all of you that took the time to help me out. The final story: 4 LO problem was in fact linkage; it had been so long since the 4 LO was used that the shifter linkage was rusted up- - WD 40 and patience took care of it. The clicking in 4 HI when turning was infact the U-joints. Again, thanks to all of you for your posts. ghs.

Great that you found your troubles! Also be aware of linkage problems if it has a body lift on it also. As Coastie stated, linkages are the most common problem, just make sure the transfer rod going from the tub to the holder is level.
