Check out what I found on my Sporty: Peabody's OBX diff thread. Scroll down the page and you'll see a few photos of my rusty needle bearings... <img src="/forums/images/graemlins/zombie.gif" alt="" /> Everything felt good after the bearings were replaced (all of them). The only issue I ran into was that I didn't tighten the front bearings according the service manual, which states the rotor should require 10 LBS of pull before turning (measured with a pull gauge on a lug bolt). I tightened mine to "feels good with a little drag". That wasn't enough. The bearings and races seated a bit more after a few miles on the road. And I had to tighten them up a little more after a recheck. Don't be like me - obey the service manual... <img src="/forums/images/graemlins/baby.gif" alt="" />
