obviously further discussion of this with you would be futile. I leave the comments below for others to consider before attempting this type of repair procedure

I agree that what you did works BUT it's like one of those hillbilly "I fix'd it!" repairs. If I paid someone to fix my car and they did it that I'd be apoplectic and incandescent!

Removing the "strut" (coilover in UK) first is the proper way to do this. The TRW (OE maker) upper arms are £50/$80'ish, fit perfectly and you almost certainly won't need an alignment afterwards, especially if you use a Sharpie to outline the coilover retaining bolts and centre them back during refitting.

You can download the Porsche parts catalogue, in German-English, from http://www.porsche.com/usa/accessoriesandservices/porscheservice/originalparts/originalpartscatalogue/

Select Cayenne from the Model drop down and then pick the Year and click the Display button, the site then sends you a PDF file, roughly 22Mb.

The link above is for the North America model versions, I don't know whether South America has the exact same build specs.

My CTTS has the standard red CTTS brakes. If his has the optional yellow PCCB then it might be that only 21s will fit, PCCB are 420mm front discs on an '09.

Yes, it fits, I run these with winter tyres on my '09 CTTS.

The ones I use are 9" x 19", I think, ET60 is cut into the wheel on the front somewhere the valve stem, tyre size is 255/50VR19, Pirelli Ice & Snow in N0. I've read something somewhere that 275/45R19s fit too.

I've no idea what the situation with warranty claim rejection is like in Canada (the OP's from) but here in the UK they won't even fix things that I think are totally legitimate like front subframe bushes "wear item", seized brake caliper "wear item" and control arm bushes "wear items". I wouldn't want to advise anyone to inadvertently mess up even the possibility of a warranty replacement of a diff, transfer case or auto box given how much they cost.

Porsche dealers charge quite a lot for Porsche branded fluids. I found it useful to find out that Mobil ATF3309 is apparently identical to Porsche ATF (i think PN is) 000.043.205.28, that VAG G052515A2 is apparently identical to Porsche's TC gear oil 000.043.301.36 and that VAG G025145S2 is apparently identical to Porsche's 75W90 Diff oil 000.403.205.30.

when I changed the transfer case fluid in my 09 CTTS it wasn't ATF that came out it was definitely gear oil of some sort, it was a slightly dirty (55000 miles) but still gold just a bit browner, after checking the Porsche parts catalogue for the part number, 000.043.301.36, I crossed ref'd that to VAG G052515A2. That's what I put in my TC.

I had this exact type squeaking/whistling noise on an old SAAB 9000, it turned out the aircon air temp sensor had a tiny fan and its bearings were dry, maybe you can check by sliding a small thin cable tie in through the slot in front of the air temp sensor to try and stop the fan, if the noise stops voilá

The 3.2 v6 cayenne oil filter housing unscrews with a 36mm socket, the housing drain plug in the centre of the 'socket hex' is 8mm, if i remember correctly. I'm not sure about the 3.6 though.

If you want bolts that properly fitting bolts, the easiest way is to get them from VW or Porsche and, unless you live in area prone to wheel theft or want to have non standard wheels, I would just buy the regular non locking bolts. Here in UK VW charges about $5 a piece.

I may be wrong but I'm sure I've seen the spline type bolts on Touaregs. VAG (VW+Audi) UK definitely sell the keys with one replacement bolt, I know as I bought spares for Audis from them.
