Alex' suggestion might be a good first step. Please be cautious when ordering bushings and links for the Turbo S, since you have PDCC as part of your standard equipment. Active suspension parts are different from regular ones.
I actually was in a similar situation as you are with a what used to be a 200K$ car making sounds like a beater.
If you want peace of mind, order the following. I just did it and my car now drives like new.
A] 2 new upper control arms (Lemforder 3568201KT)
B] While the lower control arms each have 3 bushings in them, only 1 of them needs to be replaced on each side (Lemforder 3572901). This is an expensive bushing which runs about 80$, but the alternative is to replace the entire control arm, which will set you back over 300$. Replacing the bushing will require you to find a local shop with a special bushing press, or you will have to build your own homemade contraption.
C] The swaybar gets trickier because both the parts and torque settings differ whether you have active suspension or not. Please also be careful to support your swaybar when you lower the X-brace. Unlike a regular swaybar the PDCC one is attached to the electronics of the car.
Cars equipped with PDCC :

• upper bushings (Porsche 97034379207)
• lower bushings (Porsche 97034379307)
• links :
  • Lemforder LEM-3568002 ; OR
  • Porsche 97034306921, 97034306923, 97034306922

Standard suspension :

• upper bushings (Porsche 97034379205)
• lower bushings (Porsche 97034379305)
• links :
  • ​​​​​​​Lemforder LEM-3567902 ; OR
  • Porsche 97034306903, 97034306902

Hope this helps.

 

FYI - I just had the front upper and lower control arms replaced in my 2011 Turbo. I had a well respected independent shop do it and the total labor cost was ~$1325, which included an alignment. I was going to have them do the sway bar bushings while they were in there, but Porsche sent them the wrong ones. They took mine out, said they looked good, greased them, and put them back in. Everything turned out great, no more crunching when I go over bumps...

 

Good to hear. Come back in 3 weeks with update.

 

Thanks guys, I will try and look to see what I need first! Bill

 

Hello trying to reach you for assistance with clunk on my 2011 4S......please advise best way to contact you.Thanks!

 

​​​​​
He's kind of disappeared on me also, sadly. I sent a PM asking if everything is alright, but got no response....

 

If you're trying to reach members, best way is via pm. Plus not obvious who you're trying to reach.

clunk in suspension can come from torn bushings in upper or lower control arm, or even from sway bar link, but would be much less pronounced. If no work on car was done yet, chances are both upper and lower bushings need replacement. Upper arms very hard to diagnose on car, have to remove to see rubber if broken.
I'd start vfc with lower or do both.
squeaking (like mattress) is often caused by sway bar bushings bad.

 

Just got the front suspension off our 2012 Pana4. Had a squeak and a leak. Knew the strut was bad, but decided (thanks to this tread) to replace it all while I was under there. Not only were the struts bad, but the upper control arms had a torn boot, the lower front bushings were torn, and the sway bar bushings look really bad.

New struts, drop links, bushings, upper and lower arms, strut mounts, and a few nut and bolts ended up around $1700. Will post more pics when done, but wanted to thank all you talented folks on this board.

Old stuff out...



Had to pay $125 to have the 2 new bushings pressed in...!



Passenger side strut was blown.



New drop links.



Upper control arm was damaged.



Swaybar bushings look bad, but I am not an expert. New ones going in anyway.

 

Creating some polyurethane bushings for mine, upper arms and both lower bushings, thinking about doing the third bushing as well

 

Just got the last items in, and the sway bar bushings are a different size. They are the correct part number though. Wondering if I am supposed to squish them down enough, or do they need trimming??




Thanks in advance!

 

my understanding is that you'll just squish them down when you install them - I purchased the same ones I believe

 

Yes new ones are very tight.
I put red rubber grease on mine too (as that’s what the OPC recommended using).

 

Nice. That full job at dealer would likely be close to 10k. With air suspension would be close to 20k.

 

Can you take some pictures of your Panamera on the jack stands?

 

I can for sure. I have them under the jack points on each side, and then a jack stand under each axle shaft (so they don't dangle). But I will get pics.
