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?Jeepster did pass the time by typing:
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.

Jeepster did pass the time by typing:
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.

damn, given the subject line, I thought this would be a more exciting post...
I have that rubbing sound too. Well, mine is more of an air sound than a rubbing sound ...

I see that and think "talcum powder"..... :/
I'm afraid to check ...
