Tahoe whining noise

My 2001 Tahoe has a high pitched whining noise that seems like it is coming from the front end. Jacked up each wheel and spun and one front bearing sounded rough. Changed front hub bearing assembly. Road test -- same noise. Changed other side. Still has noise. About 40 to 60 mph. Can shift to neutral and noise remains. Can turn off key and coast and still has noise. Any ideas??

Re: Tahoe whining noise

start by eliminating things... I know its work, but in order to find it do the following:

remove the front driveshaft. drive vehicle, noise?

remove both front axles....most likely your noise will go away once you remove the axles....noise could be in the front differential, just guessing but once you start eliminating items you will find the problem GOOD LUCK !!!!
