Hi all. I'm Scott, (noob), I was browsing the threads, and I am actually replacing the entire rear end in my 2001 xterra tomorrow due to that phantom grinding.

It's the wheel bearing, ( at least, that's my problem.) I find it will be easier for me to swap out the entire rear end with a $300.00 junkyard part, than it is to pay for the bearing to be removed from the axle shaft.

Hope this helps someone.
