Re: High Speed Differential Whine
I had or rather my wife had a whine from the diff in a Mustang and she solved it by turning up the radio. When the radio became too loud because the whine was too great she informed me of the problem, too late for the diff as the wear pattern had ruined it. Faced with a large bill for a new diff or less to replace the bearing which had failed initially I opted for the bearing and figured my wife could live with a slightly louder radio to drown out the lesser whine which was now present permanently.
Moral, fix the bearing if that's the problem, before it gets too bad.
