I just got my aisin hubs installed and went out to see what the truck now drove like. When i have it in 4 low there is a whining noise that seems to be coming from one of the hubs. whats got me confused is that i couldnt hear the noise when i was in 4 high. what could this be?

 

I used to get a whiny noise from my old Bronco while in 4 low. I never figured it out.

P.S. Nice to see another Okie (I hate that term but hey ) on the board.

 

Make sure the hubs are actually locked in and something is not wrong with the internals.
