Squeeeeekking noise, rear end noise Options

Yes i did a search and did some research before i posted this one up. Its another annoying squeeking noise when im driving. it stops squeeking when im braking but it sounds like the car is winding down. Squeeks around 20mph or less in the rear. I just got new back rotors, mechanics said brakes have allot of beef on em so no need to change em. Im frustrated of going back to the mechanics every weekend and having them find it to no avail and making me feel stupid, even when i took them on a drive and of course no squeeks! I removed the hatch cover brackets since i noticed those were loose and made noises. I took out every plastic panel imaginable and removed every small piece laying around. Can anyone relate to this or am i just crazy.

update on problem...okay well im back with good news...i took off rear tire and find a small squeel when i rotated rotor and it need a small squeel...took off rotor, sanded down inside rotor and brake shoes...put everything back...rotated tire, no squeel, yay right? well i drove it around the block, still another squeeling noise, back to the drawing board..i took a former mechanic who is my gf's bro-in-law and he stuck his head out the window as i drive around...said noise is coming from the front...get back...take off front tire...everything seemed okay until moved the metal clip thats on the caliper and holds brake pads seems to be rattling..., removed caliper, and put anti-squeek red stuff from crc, put some more on back of pads, put everything back on...drove around, little noise but not as loud...next is to find new or better clips and try that...but so far so good.
