2000S IMS confusion

[JFP in PA]

It looks like a dual row. As you have the IMS flange cover off, look to see if there is a snap ring between the flange cover and the bearing; if there is, it is a single row. If there is no snap ring, it is a dual row, which uses an internal wire retainer.

No snap ring! Thanks for the help.

Just to help confirm, that part number (6204DUA17) looks the same as the dual row shown in the first message of this thread...

Bearing was a dual row. I replaced it this past weekend with LN retrofit. Bearing that came out was still in pristine condition, both seals intact, no play, and based on the style of bearing looks to be the factory original, so not bad for 97k miles. Rear main seal went in super easy. Thanks to everyone on the forum who has posted in the past, made both jobs super easy. They were reasonably straightforward for someone who has done some bearing replacements in the past, but always easier when you know what to expect. Built my own cam lock/removal/install/rms tools, but I have precision lathe and mill, so I was able to make them out of extra stock I had around. Still have to install the flywheel/clutch/transmission just waiting on some micro-encapsulated bolts. Winter in New England, so may as well just wait, not doing donuts in the snow with the Porsche, my truck however might be a different story.

If you still have the old bearing, remove a seal and see if there’s grease on the inside. That will indicate what it’s future would look like

No grease = no future

I just did this. The balls were in nice shape but no grease to be found.
