Re: 2006 highway howl
As it's 4wd, it could be an axle. When was the last 4x4 service done? If it was done ask to see the bill to see if the right fluid and amounts were used. If they weren't sealed up correctly one axle could leak fluid out around the pumpkin (gear housing) causing the whine you hear from lack of lubrication.
