This question is regarding a 1999 vortec in a 68 Chevy 1/2 ton (yeah I know the name of this site hehe) A squeaking sound starts coming from the main pulley coming out of the motor area about 5 minutes after the truck is started(it doesnt squeak when cold) I know its coming from there because I removed the belts and it was still noisy. The truck runs and sounds fine otherwise. If its a main bearing is that expensive to repair or can I lubricate it? Thanks in advance Syd
