Here is my 2006 CTS-V. 81k miles. I like it a lot.
-Here is the old K&N air filter and in-cabin filter.

I knew the tires were junk when I first saw the car. The brand was Fuzion UHP and I chunked a set of those on a front wheel drive shitbox from days of yesteryear. I have been a huge fan of these Nokian tires so I got these for the V.

I have little brake test strips that detect the presence of copper and I knew my fluid was garbage when I first went ham on the brakes. I was severely underwhelmed by the four piston front and rear system and experience rapid fluid fade. I know that feeling well enough.

I have learned a lot about the few weak points of the 2006 CTS-V. My chassis is pretty good less the driveshaft carrier bearing. All other mounts are good. The rubber is **** inside of that driveshaft carrier bearing that I get terrible clunking noises when torque changes abruptly in the driveline. This has relegated me to driving like the geriatrics the car was marketed for and not the LS2 engine that is strapped inside begging for more air and fuel. Rotella T6 5w-30 engine oil. Mobil 1 oil filter. The rear diff was recently done with Amsoil severe duty gear oil and the proper LSD additive. Transmission shifts smooth enough I don't feel it necessary to change fluid or do anything to that. Clutch fluid is clean and feels great as well. Just need that brake fluid changed and the driveshaft carrier bearing either serviced, a new driveshaft installed, or I spend some loot on the aluminum or carbon fiber one-piece. Looking for suggestions on what others have experience in regards to this fix.
I checked recalls and three were open, never performed on my car so I have an appointment to get those three done.
A. Front brake hoses in my salt-belt state call for replacement. I hope to get a brake flush for free also
B. Hesitation/stall either reprogramming of ECU or replacement of fuel pump module
C. The silly key ring place-filler to reduce number of keys held on ignition key. (or key replacement)
Then decide with a one-piece aluminum driveshaft or try and task myself with wrestling with a one-day install of voodoo chikin bearing. I cannot afford having the car down all that time it needs to remove, ship, wait, arrive, wait, work on, wait, ship back, wait, un-pack, wait, re-install. Just not conducive to my crappy lifestyle choice right now of not owning my own home but buying a sweet CTS-V instead.
I like my new-to-me car. I have always wanted one since I did dealer trades as a young man for Cadillac during the time when the 04 model first came out. I remember watching SCCA races where they cleaned up and then they were heavily regulated and still won. Thanks for looking.
I would guess the clunk you hear is the rear diff bushing look up Creative Steel and depending on what you plan on doing to the car buy what they see great products and even better people
Nice car and welcome to the dark side haha
