Question for the Machanics out There.
 

I have owned my Boxster since new. It has the original IMS baring. However, on July 2, 2008, at 16,452 miles, the RMS was upgraded.

The invoice states, "R&I Exhaust, R&I Transmission, R&I Clutch and Flywheel, R&R Rear Mail Seal, R&I Tensioners, R&R Intermediate Shaft Flange Seal, Clean Oil Residue From Trans and Engine."

The total bill was $2223.52 and listed the following parts;

1 - 997.101.212.00 Shaft Sealing RI
1 - 996.105.112.01 Rubber Gasket
4 - 999.385.004.01 Torx Screws 3x35
3 - 900.385.275.09 Torx Screw 5x29
8 - 999.073.092.09 Screw 10x50

Reading other posting it appears that you can tell what baring your Boxster has by looking at the IMS flange seal. Do any of the part numbers above appear to be the IMS flange seal that they replaced during this service? And if so, can you tell if it was for a single or dual baring? TIA.

Not the flange seal, but by looking at the metal flange itself (they are noticeably different). Both the single and dual row IMS flanges use the exact same seal.

Ahhhhhh.... It was a thought. Thanks for the info.

So looking at them , what is the difference between the two flanges ?

This explains it all in detail. Look at Photos #13, #14, and #15 for the differences between the two flanges.
