My 92 loyale has a funny sound coming from the rear of the car, as I'm drivng it makes a sound kinda like the brakes a stuck, but when I press the brakes it goes away.

I'd say a wheel bearing most likely. When you put your foot on the brakes the caliper grabs the rotor and stops holds the wheel tight (if you've got rear discs of course). Jack up the rear end, and wiggle the wheel, holding the top and bottom. If you've got play, time to do a wheel bearing.

 

Let us know how you get on.

thats what I thought as well, might as well do all four while I'm at it, probably do the rear shoes as well.
