Hey I was wondering if anyone is experiencing a problem my 05 kon has started to do. It has 70,000miles on it, and nothing major has gone wrong. However, it has started making this noise whenever i accelerate. It sounds like it's coming from the rear underneath and it's a squeeking noise. The funny thing about it is the faster i accelerate, the more frequent the squeek is. until i get cruising and forty or so, and the thing is just squeek squeek squeek really fast. I've been told by my buddy at GM that he thought it sounded like a U-joint. But he doesn't really work on that type of stuff, he's a cadi engine calibrater for the tom versions of the cadillac. Anyone know if he's right??
