Bro in Law has an 01 Tcat that makes a chattering sound when running, Thought it was coming from the clutch but it does not go away at higher rpms. Seams to be some play in the center piston when manually moving the primary (used a screwdriver inserted into jug and set on cylinder head to feel motion). Does it make sense that it could be the center bearing going bad? If so how big of a job to tear the crank apart? Where to take crank to have tested and bearing replaced in SE MI?
