A little rubbing is normal. Over time the pins that the caliper float on
can become crudded up or worn. If that happens the caliper might not recenter.
Another remote possibility is not having the proper shims on replacement pads.
Most don't need them, it all depends on what brand. Yet another possibility
is not removing all the stopsqueel from the caliper before putting in the new
pads. That tends to cause the pads to sit cattywompus to the rotor. Usually
results in squeely stops but can cause rubbing noises since they never properly
retract.

Jeep used a very light axle assembly with thin tubes. Jacking from the
pumpkin can put enough stress on the axle to bend it. Always jack from
the jackpoints or under the axle tube at the drag links.

It could be one of the above, but dont get fixated on these. look for shiny
metal on rotating parts, (obviously as well as brake components), even if
you cannot see what might be doing the dragging. remember that the
suspension will be lower when travelling than when up in the air.
