Trying to eliminate a cold start chirp of the belt on a 2008 Escalade 6.2L V8. Changed main drive belt and AC belts as well as both tensioner pulleys. Didn't eliminate but needed to happen anyway. I think I have it narrowed down to the alternator bearings and/or power steering pump bearings. The alt has a squeak when I turn the pulley wheel and the ps pump pulley wheel moves forward and back. Below are videos of both. Thoughts?
