i've got a jeep cherokee, which i'm building a front dana 44 for. I have a 79 ford housig and 73 chevy outters( flat top knuckles, disc brakes). i need manual hubs. I went to autozone and they have a one piece design hub ( the hub and rotor are one piece) is this the set up for full time 4 wheel drive? The part time set ups i've seen have been a two piece design( the hub and rotor are seperate) am i correct or can the one piece be used for part time 4 wheel drive also? any help would be appreciated. thaks

The hub and rotor are separate pieces, but are sold as a unit. When I did the disk conversion on my Bronco I bought the hub and rotor together.

When I went to replace the rotors on my truck I found out it was actually less expensive to buy the hub/rotor unit instead of buying rotors alone.

ford and chevy uses the same hub and rotor assembly for their parttime and full time rigs
you were asking for a manual hub leads me to believe you are looking for lockout hubs ???

The one piece units are the equivilent of the 2 piece ones, you just don't have the luxury of replacing a $20 rotor if you get all chewed up/scored by poor brake maintenence, turning them down a few too many times, etc. The splines inside the hub and the bearing seats, etc, are identicle. The full time trucks just had a drive flange/clutch ring that satisfied the same function as locking manual hubs. If you pop the cap off the hub on a full time truck it should have the same inner spline grooves for your manual locking hub body as well as the groove for the snap ring that holds the hub body in. I used the one piece hub/rotor combo when I did a disc swap on my early Bronco, because they were cheaper and on hand at the parts store when I did my swap.
