Rubbing in rear end
 

My wifes 97 Grand Cherokee has had a rubbing sound coming from the
back end for awhile and it seems to be getting louder so I took the
back brakes off (disc brakes with small drum e-brakes) and it seemed
to me that the e-brakes where too tight so I losened them up a bit.
The sound seems to have dropped off a bit but now of course I have no
e-brakes on this vehicle....... none the less I still have a rubbing
noise.

Any ideas on what might be causing this noise.
1.) warped rotors?
2.) bearing?

Worn epads, rock/dirt in the mechanism, caliper out of whack.
worn pads, warped rotor.... lots of things possible but usually
not the bearing. Unless someone jacked the ZJ up from the back
pumpkin.

The e-brake will self adjust. Yank up on the emergency
brake handle a few times and they should adjust back.

The brakes have lots of pad and the rotors where replaced on a recall
last summer.... It has got to be in the brakes somewhere as I can hear
rubbing when I jack it up and turn the tires and no noise when I
remove the brakes.

Jacking it up from the pumpkin? I have seen this done many times and
never thought it was a problem..... I do it on my YJ all the time.

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.
