Wow I've been doing nothing this for a while now and haven't heard that one. Hey I love learning new things, thanks! I don't care what they say about you, yellow rose, you're alright in my book. I cannot confirm that that's what happened but it makes sense. I remember the first time I installed the 904 it was a complete pain, the second time not so much. So to fix this I need to remove, inspect, and retorque #3 cap?? Or is my bearing and cap now trashed??
