i just installed 4:88 gears and a detroit locker in the rear and detroit ez locker in the front. from the first minute i drove it after the intallation there has been a whinning noise coming out of the transfer case? ive had plenty of people tell me its normal because of the ez locker but it still concerns me. this is my everyday driver.

 

I just have stock but my transfer case wines too, especially when it is really cold. It is only when it is rolling. I've had 2-3 shops look at it and they can't diagnose it. 4wd doesn't even have to be engaged and it gets this noise. But noise gos away when I hit 25-35mph. Any thoughts?
