i'm hearing a rotational squeak/chirp from the drivers side rear when i'm cruising down the street. the squeak/chirp lasts for about 2-3 minutes then goes away. it appears to be related to something warming/heating up. it only happens first thing in the morning or when the car has sat for a hour or so. i don't think it's brake related b/c i hear it even when i apply the brakes. i did have the rear diff resealed, recently. could it be related to that? i got a recording of it on my iphone. i used the voice memo app to record it. i dont think there is anyway to copy on my cpu. please chime in w/ your thoughts, thanks.......
