Ok today after work I actually was going to get the meter long sand mats that I ordered for my libby when I started it everything was normal except that when i drove I heard a strange sound coming from the rear wheel driver side its some kind of a squeak but it came and went like a nail in the tire getting louder and faster when I pushed the acc.
I went to a gas station and went under the car but saw nothing that could be rubbing or scratching down there
Still to check the rotor and clipper but thought to ask if anyone faced a similar thing and what I should be checking
Thanks guys

Check the rear u joints they will make a squeak...squeak sound and get faster as you speed up. Most likely they are dried up ( toast) Drive for a mile then put your hand up close to the rear joint if it's dried up it will be real hot.
If not that then check brake calipers for sticking

Well i was planning on testing the u joints like Tommud said so i started it this morning and went on driving the sound kept on getting louder but i decided that it could be safe to go on the freeway just long enough to get to work and see if the joint was burning by then or what.
25Km later i was pulling over in the parking when someone screamed stop your wheel is loose then i went out the libby and checked the lug nuts with my hands and 4 came off just by touching them

so now i know where the sound was coming from, a F#@$% guy must have tried to steal the whole darn wheel off my parked car
and thank god i made it without the wheel coming off on the highway
