I've got a '90 XJ AW4 4.0 with 169k miles. I took it on a 3 hour trip last night, and as I was nearing home, I started to hear a loud, high pitched, squeaking coming from the engine bay. The noise only happens while at idle, or when I take my foot off of the gas. I stopped and popped open the hood, and it sounds as if it's coming from a pully on the water pump or alternator. I can't really tell.
The waterpump is less than two years old, and the alternator is less than six months old. The belt is in good condition.
Any idea as to which pully might be causing this?
Thanks!
