Vibration issue, tire related?

So much smoother now...

This is what the inside of the Green Company bearing with 270 miles on it looks like.



That is metal from the outer race that has turned the blue colored grease dark.

Just for comparison, this is the inside of the Federal Mogul bearing that came with my axles 5 years ago that have about 5,000 very hard miles on them.



They still didn't have any play in them but were a little rough feeling when turning.

The new Federal Mogul bearing also turns much smoother and easier than than the Green Company bearing it replaced. I'll probably do the passenger side as well soon just because.
