Buying used Boxster S - IMS flange replaced but not IMS bearing?

[sranton]

I've downloaded the PET and searched for the part number and it shows up on page 22 (of 472). Trouble is, the PET lists "2004" in the header of all the pages. I can't seem to find any part variations (seems like the catalog is for a single model year) How would I be able to determine whether I have a single or double row bearing from the illustration? The flange is p/n: 996-105-017-02. Thanks.

In 2000 there are no accurate directives that will clearly identify which bearing is fitted. 2000 and 2001 both require a visual inspection to quantify which bearing is fitted.. Porsche kept the records and did a poor job of it based on our direct experience.

The IMS flange was changed from a single O ring style to a triple lipped style seal due to leakage issues. That said, the fact that it was changed tells me that you have an early 2000 MY and that would indicate a dual row IMSB is fitted.

I have never seen a single row bearing fitted with the early O ring style flange. After 399 retrofit procedures, including the very first one, well, we still continue to break new ground.
