I have a 2001 f250 4x4 about 4 months ago I replaced my pass. side front wheel bearing unit and here recently about 3 to 4 weeks ago I get a grinding/ rubbing sound when ever I turn right it gets louder the harder the right turn I do not seem to notice it as much moving at speed but driving through parking lots and slow speed right turns I can hear it. I have checked everything and nothing is loose and I can not see any signs or fresh rub marks on anything.
im getting to the point of just buying a new unit and replacing the one I just replaced. I think that is my problem I bought a cheap 85 dollar unit from rockauto from a company I have never heard of before. and I think I got what I paid for but just in case would anyone have any idea on what my problem could be?

 

How was the dust shield? Quite often they are rusty around the bolts. It could be rubbing slightly.

 

Manually lock your hubs, but do not engage the transfer case. Test drive and see if the noise changes.

 

I checked the dust shield and it still looks like a rusted pos hahaha. I will try what thomabb said and see if that makes a difference. other than that I am just drawing straws at this point.
