When you removed the seal, what was the condition of the race and ball bearings? What it still packed with grease or oil? thanks

Casper Labs Ceramic IMS Bearing
holden997 replied to valley996's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
I'm interested to know what was the initial source that triggered an IMS bearing to fail? I know a lack of lubrication is the final step to the death of the bearing. There seem to be a lot more engines with the "6204" bearing failing than the revised larger "6305". I suspect the covers used on the "6204" are not the same design/quality as the ones on the "6305". I believe the better seals on the "6305" is preventing oil from getting into the bearings and washing out the grease. On the weekend while doing my clutch, I decided to popped out my IMS flange to inspect the IMS bearing and from what I can see, there is no play, no oil/grease seeping out of the seal, there is no crack on the seal, the plastic looks very good and when I spun it, I can feel the resistance of the grease so the grease is still in there. This is the "6305" bearing. What is your opinion on this? -

Caution: with the new PFTE seal (997 101 212 01), according to the WSM, it must be dry fitted (no oil, grease or lubrication). It will destroy the seal. I'm in the process of developing a RMS seal tool for the DIYers, should be ready in a week or so.
