ok i have been hearing a noise on my 97 GTP 140,000 miles, i found receits for new bearings all around vehicle for a few years ago. The sound is when i let off the gas doing 20-35mph, it is a metal to metal catching sound, no lights on. I hit a bad hole last week and i grit my teeth and now it has been doing this grinding, sould it be the hub or strut. I have 245/45/18 tires brand new no rubbing. My front rotors have been warped for 2 months now but it never did this before so i dont think its the rotors, im saving for slot drilled style. I need some help figuring this one out...and thanks for helping me out everyone on my bad gas mileage problem

....so if you can throw some things to check it is on the passenger side it seems as well in the front....thanks
