NOISE

Toyota Other

I have a 1993 Toyota 4X4. It sounded like valve adjustment tapping, but I checked it and it was fine. Then it got worse, and I could feel it in the stick shifter. I pulled the transmission/transfer case, and the input shaft feels tight, the crank feels tight, but the release bearing and pilot bearing make noise when spinning. The clutch disc looks fine on one side, but on the pressure plate side, the plate is grooved, and there are deep marks where the release bearing engages the fingers. The flywheel looks fine, but when I drained the fluid, the transmission oil looked good, the transfer case oil was grey. The rear driveline to transmission companion flange has one bent ear. Do you think it is all in the clutch components, or should I be concerned and break the case open on transmission/transfer case? It is a W56.
