My truck has developed a squeaking or squealing noise as I slow down, it's like a chirp chirp chirp. I may also be there at higher speeds, but my hearing is not the best. I do know I have lame front bearings, but here is the kicker. It does away if I add a little power or depress the clutch. I can't get the noise to happen just by rolling down a hill and turning doesn't seem to affect it. I just had a new flywheel, clutch, and throw-out bearing installed. I am taking it back to the shop on Monday, I was just wondering what some opinions were on the cause. I'm guessing it's related to the throw-out bearing and not the wheel bearings, but there is a lot of play in them (waiting on my new ones)
