So, I have a 2013 991 Cs2 and I am hearing a squeaking noise on the front top shock tower location (both towers) when driving. It sounds like poly bushings creaking.
It is a CPO car, but can I spray silicon, Teflon or graphite to make it go away or should I take it in and "get it fixed" under the CPO

Hi HkPlinker, yes, you can see it done in the video here:

I sprayed mine with white lithium grease from above and below and it worked perfectly.

So, I used high pressure grease as in the video and the squeaking is believed to be in the lower arms. I then used a spray lithium grease on every rubber component I could see associated with the suspension yesterday and let it soak overnight. Well, this morning after 15 minutes of driving it came back. I just re-visited all lower rubber and letting it sit for a couple of hours to test again.

any thoughts?

I hope it's not the squeaky gas tank issue? Search some recent/old threads on the topic.

I don't think it's the tank. I reached inside the wheel and could "feel" the lower arm as it clicked. I may need to left the front and paint brush the lithium on.

If that doesn't do the trick, It's off to Porsche for CPO action

Funny you said that. I thought so too, lubed the top of the struts, and it was the tank pads that were squeaking in the end. No matter, dealer job..

I'm betting $100 this is the squeaking pad issue.

My upper strut mounts were squeaking, but the dealer replaced the tank pads. After the squeaking came back, I sprayed some 303 Aerospace Protectant on the upper mounts and the squeaking has been gone for a couple of years now.

Post a video of the noise while driving, please. If it's tank pads, it's very distinctive.

I'll have a video tomorrow. The noise starts up after the car gets to temp and I drive for a few miles. It is much louder when driving straight. When turning it stops or is very slight. When I park the car, I can get out and push down on the front bumper and I can hear both sides (mainly the driver's side) squeak away. . . .

Any help is appreciated.

Anyone ?

That is nasty!
I can see why you're desperate to find a solution.

Hi guys, I plan to do this simple project this weekend, as the car sits with the current virus and "Stay At Home Orders". From my picture, can you please tell me were I put the grease? Thank you.:
