Juste a small testimony on this topic. As my PTT had to renew the Porsche Approved warranty, I mentioned a front noise over bumps.
It took a long time for fixing it. 3 weeks in the shop and they changed everything : lower and upper control arms, sway bar and finally air struts.
So far so good, noise is gone. PTT is good to go for one another year of PA.

 

Just got my 2013 with 17k miles on it back for the same issue. Seems like the clunk over bumps is gone now - they found the bushings on the upper control arms to be bad/loose.

 

The website InsaneGarage.com has a post that may seems to address the front end noise issue. (I have just scanned this thread so I apologize if it is previously mentioned or it is off base to the thread). That post and related issues are also addressed in the following video:

Yes, I've had tire slipping when making full turn on wet road when air started almost freezing and I still had summer tires with only 4mm thread. Changed to new winter tires and no slipping anymore at the same scenario.

 

creaks when turning ? I hope I have found the reason .... Was twice at Porsche dealer/service and twice they reported to me that suspension is ideal ... So for Porsche it means ideal ? Or its ideal while is covered by warranty ?!

 

Porsche confirmed that this drive shaft play is normal, and it has to be like that, and it can be very different on other side ... I'm

 

I've got an 11 4s that I just picked up and had the same distinctive noises up front, especially when cold, especially in the morning. Mine sounds like an old spring mattress. Luckily it has a CPO warranty from previous owner. They are replacing upper and lower control arms up front. Lets hope this fixes the issue.

On another note, I also mentioned an erractic tach needle to the service tech. At cruising speeds, the needle sort of wiggles up and down, though I don't feel the engine surging. Anyone else had this happen to them?

 

Have you checked drive shafts/front differential what is shown in my videos ?

 

Make sure they check and/or replace the sway bar bushings. They are a known culprit.

 

I have a 970TT and i've notice in the am esp when its kind of cold outside when i drive over speed bumps my cars makes a kind of noise.. is this bad? I have the air shocks.

 

After reading through this thread I noticed that all of you have all wheel drive cars and air suspension PTT and 4s. Did I miss any rear wheel drive cars here?

 

RWD here and no air suspension. Just bought a 2010 S, 61k miles on it. Lovely car but lots of front end clunks. Going to live with it for now but will be addressed in time.

 

Yes. 2013 S in the shop right now for control arms and sway bar bushings. I do have the air suspension.

 

 

Most likely clunking coming out of lower control arms bushings being shot. Hard to tell but possible.
Squeaking is most likely due to upper control arms bushings shot. These are usually the ones on either side of shock and very difficult to detect damage as they are squeezed between metal and you cannot look between at the rubber.

From my experience sway bar bushings are last to cause this. They have so little room to move, and are very tight already.

I am sure your dealer will tell you both, if you have these noises.
