Scratch that, it's not a locker it's a full spool. I hear road driving, especially turning can be tricky with a spool but I am willing to try it out before I change (it is not my DD). The pinions rotate with no problems and the brakes are complete. The hubs on the 44 seem to engage with no problem. They both look really clean. I'm gonna change the fluid in them and take a peek under the covers before I bolt them up to the jeep. I got burned on a couple of 44's i bought local, one was covered in grease so I couldn't tell the housing was cracked and another one had been a full size ford shortened for a bronco II. The tubes and the housing were good, with the flat top knuckles be the shafts were shot. I was going try to piece together one good axle out of the spare parts until I saw this deal. Glad to see the responses are from the square headlight crowd.
