Did you actually diagnose it?
Many things cause noise on rotation.
Bearings usually growl.
My experience also. Usually when I get a tick every full rotation with the tire on the ground, it is a stone stuck in the tire tread if I'm lucky. If I'm unlucky it is a screw stuck in my tire.
The way I check the hubs when I'm suspicious is to jack up one side of the front differential, remove the tire, put two lug nuts on backwards to hold the disk solidly in place, pry the pads away from the disc (carefully so as not to damage them) and try to rock the disc back and forth. Rotate the disc (axle) a few times, you can often feel the growl rather than hear it, the bearings get raw. Push and pull on the disc a few times. If there is any play there you will feel it.
Usually any the time my hubs are ready for replacement they are pretty far gone, the slop and play isn't subtle.
I think I have a front hub going out now as a matter of fact, Or maybe it is a front axle U-joint. It is early and subtle, hard to tell sometimes. Though (I think) I have heard what sounds like my right front brake dragging slightly when I go around a corner, likely a hub (disc and tire) shifting. I do have a slight bit of wander in my steering, another sign of a bad hub.
I usually go with the Jeep numbers and cross reference to whatever retailer I'm buying from, it avoids confusion.
5300 7449, HUB and BEARING ASSEMBLY, Front Brake. Difficult to find in the Jeep parts catalogue, they are in with the brake parts. Only one listing for 91-92 I could find. Always a disclaimer with my parts number recommendations, I have old eyes and sometimes they lie to me, always double check.
