identifying lockers

Hello jeepers! I am a novice and am about to ask a very basic question so please be gentle. I have come into posession of an old jeep. Some work was done on modifying it, but it was done by someone 3 or 4 owners distant so I can't ask them any questions. I am trying to figure out if it has a locking differential. The guy I got it from said yes the axle locks, but he knows even less about jeeps than I do, so I think he may have been confused about the difference between "lockers" and "locking the hubs" to engage 4wd.

Is there any kind of easy way for a layman to tell if the differential is really locked or not? This is on the front axle. When I lock the front hubs and engage 4-wheel drive, the jeep is definitely a lot harder to turn and needs a bigger turning radius than when in 2wd. Is this a good sign that I have lockers, or is that something that would happen in 4wd anyway?

Kevin Greene did pass the time by typing:

First off, never run in 4wd on dry or wet pavement it will break things. You most likely have a "part time" system. That means it locks and is for use on dirt/loose gravel/deep snow/mud.

Help us help you, what year/model is your Jeep.

As for how things work, Tom posted these links a while back

Guys, I understand what lockers are. What I am trying to figure out is how to determine if I have them.

Well, Kevin, the old fashioned way (and Bill, you back me up on this) is to jack up one rear wheel, then jump in the truck, start it up, put it in gear and try to drive away. If the one lifted wheel just spins, then you don't have any type of locking diff. If if jumps off the jack and takes off..... I think you get it.

LOL! Yeah, that'll probably work! :-D It might do less damage if you jack up one wheel, put the truck in neutral, and try to turn it by hand. If it turns, you're not locked. While you're at it, you can turn the wheel exactly twice and count the driveshaft revolutions and you will know what your gearing is, too.

Thanks. I will try this. Jerry's solution also would have caused me additional problems, because remember, it is the FRONT axle I am wondering about. (Although I suppose I could have jacked up the rear while I was at it....)

Anyway thanks again Jeepers!!

PS TJ - I assume you mean to put the transmission in neutral, but the transfer case in 4wd?

Jack up both wheels in the back and then in the front.

With both wheels in the air, turn one tire.

If the tire on the other side turns in the same direction, you have a locker or limited slip, if the other tire turns in reverse, you have an open diff.
