I noticed the new NSK bearing I got from FastLane has more resistance than the original bearing. Its smooth, just turns with some more force.
Is this normal? I know one bearing has zero revolutions on it and the other has several million...but I wanted to check.

The driveshaft (and bearing) (the engine too) actually rotate about a million times for roughly every 800ish miles you drive (with the 3.07 diff)....so if that was the original bearing and has 206k on it...then it has spun probably over 260 million times!  I have already put 410 miles on my new setup, and its running smoooth.
My new bearing also had more resistance than the old one....the old one still spun perfectly smooth though. It was beginning to corrode and rust though. And the force to get it off with the puller....yeah! I was pulling HARD on my 1/2 drive ratchet on my 5-TON bearing puller....and then it finally popped loose.
