Porsche intermediate shaft bearing failures are one of the most talked about issues with the 996 and 986's with the M96 engine. During the design and product selection process, Porsche chose to save a bit of money by selecting a less expensive bearing that was "good enough". Time has proven, however, that the bearing selected was simply not up to the task and the resulting failures have cost owners huge sums of money.

So it never surprises us when we have customers who want to skip the worry about IMS bearing failures altogether and replace it as soon as possible. Such was the case with this 996.

The trickiest part about IMS bearing failures is how random they can be. We have seen a well maintained Boxster have a catastrophic IMS bearing failure with under 40,000 miles and have changed a bearing in a 996 with over 100,000 miles that was still in good condition. But when talking about a part that can cause thousands in damage if it does fail, security becomes incredibly important. This 996 decided to completely eliminate that concern and now, instead of spending his time worrying, can spend more time thinking about how awesome his Porsche is.

3-2-1 before KK chimes in and says how you should've cleaned the transmission case. I do see that you cleaned the IMS/RMS area so he can't complain about that at least this time around.

Does that include the New flywheel and clutch kit ??........ >>>>>

GMP - Matthew

Thanks for asking actually. The fly wheel bolts are included but not the fly wheel itself or the clutch kit.

We will install the flywheel and clutch kit for free but the parts are not included.

Price of the flywheel and clutch kit depend on which brand and model flywheel and clutch kit the client wants to order.

Just stopped by my Indy (here in Indy...) and he is doing his first next week. It will be interesting to hear his thoughts and get a price from him.

Thanks, Matthew!

That is so funny. I was thinking the exact thing when I saw it (well, at least they cleaned around the IMS area).

Seriously though, I enjoy changing the IMSB so much, I would do it for free all day. Great pics guys.

Im actually interested in their Powerflex suspension bushing kits. I wonder if they are worth changing to? It would be nice to replace them all and feel the difference.
