3rd gear knock Updated 6-5-12

Kevin, you can pull the housing while the engine is in the car but, I don't see how it could make the noise. The housing is stationary and don't move unless it is broke to hell.

As long as the transmission is installed and the input shaft is in the pilot bearing, it could make a noise. This is the only part that is directly affected by the clutch disk and the input shaft at the same time. Not having the driveshaft attached will only change the sound because of the difference in pressure on the input shaft. Side forces in first and second might keep the input pushed into a position that would keep the bearing from making any noise. Pushing the clutch in would stop the input from turning and possibly stop the noise. Since the noise is only in third and not even when the tranny is in neutral I would check it next time you pull the tranny. Simple check, just pull the 12 bolts out of the clutch housing (pressure plate) and turn it. Any roughness could cause a terrible noise even if it feels pretty smooth. It should be replaced if any roughness is felt or just for the necessity since it is a 5$ bearing and is probably available locally at some parts distributors or bearing houses. Ask for part number A-6203 or just plain 6203.
