front lower control arm removed (from another side looks +- the same).
as we can see from photos both inner and outer bushings (No.4 & No.3) are covered in oil and that oil is definitely from bushings because everywhere around them was dry, but I couldn't find even one single crack on them ....
and it means that No.3 is hydromount as well ?

 

Update on front lower trailing (not 'control' as per Repair Manual) arm:
I've found from where came that oil around these bushings (and bushing no.3 is simple bushing, not hydromount as no.4) ... it sounds unreal, at least for me...:
oil was sprayed by mechanic at Porsche dealer when I complained about all those noises from front suspension ...
so.. because I have both arms removed from my car I made decision to go for some kind upgrade (that I have done on my other 'push to the limits on weekends' cars ) even when I found that those no.3 & 4 bushings are in good shape and no.4 hydromounts are from year '14....
I removed them and replaced with custom made from hardness 90 shore A polyurethane. Should last forever and without any noises !

 

Good stuff. I appreciate the update on both what you are doing and where the oil came from. I wish I could say I surprised that a Stealer tried to randomly spray oil on "stuff" to try and any solve your issue but sadly...

 

Where do you buy those blue poly bushings for Panamera? Can you get a complete set to replace all?
Thxs

 

... locally by my friend fitter

 

old vs new Front Sway bar bushings

 

continuing ...
front upper wishbones, all 4 had the same cracks

 

replaced with custom made bushings from the same one hardness 90 shore A polyurethane

 

removing of rear bolts from front upper wishbones is some kind like a challenge, especially on passengers side, try to locate a nut bellow those cables .. or maybe on non turbo s pannys it is different ..

 

This is really great work. I'm watching intently.

Thanks!

 

.. and one more remark, regarding eccentric screw (No.5) and washer (and maybe a nut)... I found two of them damaged on lower control arm...
97034121700 eccentric screw M12x1,5x97 - 9 eur
99633121900 eccentric washer - 7 eur

 

My 3 week old '11 PTT had the dreaded front end creaked. Dont know how it passed CPO but unfortunately I got it out of state. Had control arms replaced this week at local Porsche dealer---what a remarkable difference. Driving around town in comfort mode is an entirely luxury experience now. Don't worry though I still gladly hit the sports + on the highway. So far the CPO process has worked out.

 

.... congrats that it is sorted now !
but which control arms were changed? top? bottom? or both?
and what about sway bar bushings and end links?

 

From different owners on French Panamera forum, cracking noise is mainly due to lower control arm bushings. I've got mine replaced almost 2 years ago from same reason and noise has not come back yet.

 

My repair report---hope this helps
