rear growl - also unrelated squeaks when brakes aren't applied-goes away when are

First post, so I hope this is right area of forum.

I took my 2002 GrCherokee QuadraDrive in for a slight growl coming from the rear on very sharp and tight turns, especially U turns. The growl is not loud usually but sounds like something is not right. It won't do it when cold out (below 40 degrees) Two mechanics agree something not right and then discovered both rear axle seals had lots of buildup from probably a small leak.

They replaced the axle seals and put a differential additive in to see if it fixes the growl. They also replaced the rotors and put brand new thermo quiet pads on. The vehicle was under warranty for the seals and growl, but not the brakes, so I'm very gracious for the rotor and pad replacement for free.

Problem is now the brakes squeak when I don't hit the pedal. Very noticeable and annoying. When I apply brakes the squeak goes away. Is this normal that a squeak is now heard when not applying the brakes with brand new rotors and pads? I have heard of a new brake squeak/break in period, but isn't that supposed to only be when you apply the brakes.

Any ideas:
-- Growl not fixed - still happens only on very tight slow turning
-- Squeaking while driving goes away when I apply the brakes

Thanks for any help or ideas on what to do.

just guessing...but squeaking goes away when you accelerate also, squeaking only really when your driving at idle? I had that problem too. I took my calipers completely apart and regreased my caliper guides, and the locating studs, the ones that have the bolt holes in the back. After that, no squeaky squeaky.

Thanks for the heads up, I'll give that a shot after 500 or so miles. A friend told me to wait a month and see if still squeaking. Still don't buy that though.. I owned a '99 GC and had rear brakes and rotors done, let alone many other vehicles over time w/new brakes. I never heard squeaking when just driving and not applying the brakes.

It's got to be in the calipers. I do notice when changing lanes or beginning a turn, the squeak tries to go away, then I hit the brakes and it goes away completely.
