2005 ram. At about 60 kph or 40 mph i'm hearing a whine from the front end. Sounds like a bearing gone bad.
I have changed both hubs and the noise is still there. I have decided that it must be the diff. Has anybody had any experience with these going bad?
This is an AWD truck, are the front diff's any different for these?
I have decided that my best bet is to find an entire used diff at a scrapper and swap the entire thing.
Any info would be useful

 

U joints? Fluid level?

 

Fluid level is fine and the CV joints seem fine to. Recently had them changed.
The noise is when I'm going in a straight line.
