02 Santa Fe Rear Rotors, replace 1 or both?

My 2002 Santa Fe rear brakes squeek, but not when applying brakes, when the brake is released. I've had a couple garages check it out, and they say there is corrosion on the rotor rubbing (not the braking surface itself) and that resurfacing or replacing would fix it.

This is a 4WD we tow with. Should I replace both rotors together? Or can I get away with just one? (I'm replacing the pads on all four wheels.)

You need to replace rotors in pairs (same axle). Failure to do so could result in uneven braking ability between the two sides.:eek: That could be a scary situation, especially when towing. If these are original rear rotors on this 2002, you definitely got your money's worth out of them.
