I've had a chirp/squeal under hood and I've having a hard time narrowing down the source. I wonder if it's the alternator bearings. I'm kinda new to working on my truck so this might be a dumb question: I've read that you can squirt some lithium grease in the bearings...How do I do that? I'm not sure how to get at the right spot.
BTW, I've already replaced the serp. belt, idler pulley, and belt tensioner.
