This article describes with photos how to replace a wheel bearing using the SIR Tools B90-P2 tool. There are no other "step by step" articles on any forums, so this article complements the others you find on the Internet to show how exactly to do it with this particular tool.
Step 1. Remove the wheel carrier from the car. This photo shows where this article starts, it is specific to removing the bearing, not removing the wheel carrier.
Remove the wheel hub from the carrier, these three photos show how to put the tool in place. Basically, you draw the wheel hub out of the inner bearing race, it comes out easily.
Remove the bearing from the wheel carrier. Heat the aluminum wheel carrier to 100 degrees Celsius, do it evenly, it takes about 3 minutes, measure the temperature with an infrared thermometer. Note, there are other articles on the Internet which use the wrong standard for temperature (they incorrectly say Fahrenheit, it should be Celsius as per the Porsche Workshop Manual). Your basically drawing the bearing out, into the large cylinder. You can use the wheel hub as a support and conveniently turn the bolts with your 24mm and 27mm spanners.
Insert the new bearing into the wheel carrier. Prior to doing this, clean the bore of the wheel carrier with polishing cloth (your just cleaning it, not removing any aluminum). Put the new bearing in your kitchen freezer overnight prior to inserting it. This is an alternate approach to Porsche Workshop Manual which has you heat up the wheel carrier to 100 degrees Celsius. The freezer method is easier on your hands since you don't have to touch hot metal (if you do use the heating method instead of the cooling method, wear work gloves as usual). The tools in this step apply force on the outer part of the bearing and the aluminum casting. The photo shows the bearing half way in.
Insert the wheel hub into the bearing. Remember to put the splash shield in place prior to actually installing the wheel hub into the bearing. Notice how the tools thrust bearing which is silver in the second photo below is used with the smaller circular die. Basically you draw the hub into the bearing with force being applied between the inner race of the bearing and the cast iron wheel hub.
Re-install the newly restored wheel carrier into the car (this is not covered by this article since there are many others on the internet).

I purchased an '04 CTT about a year ago and have been slowly bringing the technology up to date (rear view camera, up-to-date stereo)...
I am interested in adding TPMS, and there's one that is compatible with my Apple Carplay stereo:
Was wondering if anyone else had success using something different. There are plenty on eBay that use bluetooth and a simple Car-Lighter plug-in monitor (which would work for me as well):
Just for fun. Recently had my 120k mile service completed for my 04 CTT. Clean bill of health and ran good sounded better felt great. Soon there after I happened across a gent in a Viper truck, coming up behind me fast flashing his lights blowing his horn and then pulls along side window down and thumbs up. I think to myself, " ...man I too old for this sh*t...", but give him a go anyway. PSM off, suspension lowered and to sport, 3 horn blasts and floor it! After a huge breath and accompanying roar and turbo lag, it's 1st gear and off we go! Needless to say it was fun. More to say after he caught up; "...that's not stock!" No it isn't I reply. So as I let him speed of I continue my leisurely sub 60mph drive home. Along the way I get PSM failure visit workshop. Okay...next up check engine light. Hmm...next up tranny lights up like it's in safe mode but is audibly and physically shifting fine. Temp is a little higher than normal and hmm...no more than .3 bar boost at WOT? Okay what did I break now? SO, at home codes pulled: 2187, 2198, 2281, 0299.
Okay smoke 'em! Turn out I've manage to "break?" the old worn out breather hoses and the intake distributor is leaking! Gee Bevis...anywho fun weekend for me! So, while I'm in there I think I'll swap out the diverter valves and control lines as well. Just wanted to share.
Hi to all in the forum, I am Chris from Greece and I am looking for a piece of advice.
I have found a CTT 2005 with 35000 miles that a bank sells after being abandoned for 2+ years and not in garage. As the price is tempting and I am looking forward to spend some cash to bring back to the road.
What do you thing I must expect in terms of Service, taking for granted that all liquids in engine and trans are going to be replaced, new tyres etc.
P.S. probably a conversion to 2007 F/L look is a thought. http://www.renntech.org/forums/uploads/downloadedimages/edit.gif' title="Edit/Delete Message" alt="edit.gif">
