Thought I would pass on some info. After installing my new SE Comp I got a whirring sound and slight knocking within the primary. Turns out the Inner Primary Bearing was failing on me. The tell tale sound is a whirring sound and a slight knock heard from the primary.
If you do hear this, the first thing you want to do is pull the drain plug to the primary. It will be loaded with metal. After that removing the outer primary cover you can look at the forward radius of the starter ring gear and if you see a witness mark that follows the radius of the ring gear. Well its a bad bearing.
Most likely the IPB .
I popped the inner seal off and found metal flakes laying between the snap ring and seal. The bearing is falling apart internally.
Sometimes it can the clutch hub bearing going bad. That can be check by removing the clutch pack and moving the inner hub for runout side to side or in and out.
You also want to inspect the IPB race and make sure it hasnt walked inboard. You need a gap of .100 between the transmission seal and the lip of the race.
