The jeep has a 3' lift with 31' mud terrain tires on it right now. So, the XJ is my play toy but could be (and would be) used as a backup vehicle if I needed to go somewhere and the wifey is gone in 'her' car or she may drive it if we get a bout of snow/ice in the area for more ground clearance. It has 3.55 gears (and I dont plan to regear in the future.I did that with my YJ and it was a HUGE mistake).Īnyway, the jeep isn't a DD (I have a work vehicle, my wife has her own car). I have read many threads on the 'never ending which is better: front or rear' debate and am no closer to making a decision. Now I can get fantastically stuck.Īt some point I'll switch to a front elocker but that will most likly be a few years down the road.So I'm starting to research lockers for my XJ. If you are not regearing and don't plan on flat towing you can install a lunch box locker without having to setup your ring and pinion so that option might make sense. Locking hubs are $1500 plus $500 to have installed and an elocker is $900 plus $450 for the install. An elocker would solve this as well as I could just unlock to an open differential. I also occasionally find it easier to drop out of 4wd on the trail for a tight turn but I havenot found that I have to go to 2wd. I don't mind the rear spinning as it drives the oil slinger in the NP231.

There are a few out there that are limited slip when disengaged but they would still spin the driveshaft when towed. I can solve this by adding locking hubs or switching to a selectable locker that is open when not engaged. I also now have to remove the front shaft to flat tow as the YJ NP231 transfer case outputs are connected with the transfer case in neutral. After spending an additional $250 on a standard shaft from Tom Woods I can drive at 70 MPH with slight but noticeable vibration. I had considerable vibrations above 45 MPH at first due to the factory front driveshaft not being balanced. I did not consider the fact that the locker would spin the front driveshaft in 2wd when I installed it. I don't have any clicking in 2wd as the CAD disconnects the passenger side wheel.

I have a True Track limited slip in the rear as well. BLUF (Bottom Line Up Front): If I had it to do over I would have saved for a selectable locker like the eaton elocker for the front.
