It is the single row for the 00 to 04 cars... and yes... it is really expensive

You better check the application for a specific car with the parts guys at the Porsche dealer

It was listed at about $500 at Sunset. Not cheap. But for a small fistful of dollars more, you can get an LN retrofit.

I know that thread sealer is used. I'm was pointing out the use of torque seal, which is used to check the bolts and nut for any loosening. I use torque seal on nearly every fastener in my planes, but I haven't seen used in most auto work. I'm comfortable qualifying myself and performing the work. I appreciate your feedback.

I've been trying to piece together little bits of your posts to build a picture. I figured you may have messed with planes. Do you have your own plane(s), or work on them? The Oscoda connection is what has me curious. Do you have a connection with Wurtsmith, or their air museum?

It's been a while, but we used to compete in autocrosses at the airport there. Great site and good vacation country.

Oh, and yes, I cleaned the area, but hard to tell if oil contaminants was from IMS or RMS.

Ok, so by "Torque Seal" I assume you mean something like Loc-Tite (thread locker) - it looks like there's some red stuff on the center nut). It's not recommended in the instructions for "The Solution" - And I certainly wouldn't use "red", as that's generally reserved for connections that are never to come apart. In any case, whatever you decide, I hope it works out for you. Good luck with the work

Hey Scott. Yes, since retiring from the Navy I have build four experimental aircraft and restored another 5. I currently own and fly a Titan T51 Mustang (profile pic), which I restored a few years back. I also share a Bonanza A36 with a Buddy. Yes. I hanger both planes at Wurtsmith and have the privilege of flying from a beautifully new 12,000' long runway. Fast cars and planes right!

Well, not exactly. Torque seal is used to "mark" fasteners, both on the fastener itself and and the face of the seating surface. This forms a bridge of torque seal which is visually inspected to ensure that the bridge is intact. If not, the fastener has moved. The three flange fasteners and the nut had torque seal placed on them, which washed off when I cleaned the area.

ASSA still runs three to five events yearly hear, which are great to watch from the ground and from the air!

I have been able to determine that the IMS bearing was replaced and that the OEM flange was reused. Unfortunately, I am unable to determine what replacement bearing was used, when the work was done, and by whom. I am replacing regardless along with all many other preventive maintenance components.

Ahhhhh... I can be a little thick sometimes! I've always called that "nail polish"

Not familiar with ASSA. My google did not find something that makes sense. Is this cars, or planes? If cars, you probably mean SCCA. That's the club I belong to and run with.

Here are a couple of shots from a couple of my most 'recent' trips to Wurtsmith.

Sorry...I should read what I type prior to firing. Yes....SCCA! Those are great pics and looks like such great fun. I ran a buddy's 1986 911 SCCA when I was stationed at NAS Pensacola. Fantastic fun!

IMS bearing replacement went very well; surprisingly straight forward process. The existing bearing appeared fine, but I replaced anyway. I used the Pelican bearing. I don't drive my 911 for five to six months during Michigan's winter weather. So I plan to replace the IMS bearing every two years regardless of mileage. I enjoy the work and have plenty of winter down time for engine/trans drop. Appreciate everyone's guidance.
