Growl coming from front end

Noticed recently that the front of the truck has much more noise while driving since I put the lift on."almost like I have mud tires" Today I hit the switch for 4wd and noticed the noise went away. Seems like I remember a thread about a bearing going out and causing a shake in the front that goes away when 4wd is engaged but cannot find it. Mine does not shake but I do feel a bit more vibration in the pedals. Any suggestions?

 

Front diff needle bearing is the usual problem. Replace with ECGS bushing. Here is the gigantic thread you were remembering:
