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?
