SO my truck has close to 40 thousand miles now with a case of noises. My exhaust muffler finally is rusting out and pieces are breaking loose and rattling. Also the motor is making a funny noise and that's what concerns me the most. its a high pitch whine, its around 2,000 rpms and up. it sounds like several things to me; alternator, fan belt, or a belt tensioner.
Has anyone else had this problem?
Im going to try and record the noise from under the hood and maybe somehow post it so everyone can hear what it sounds like.
(attached is a picture of what came out of my exhaust on the right and on the left is a quarter to compare.)
