Hi all. Has anyone dealt with REAR suspension creaking? I’ve searched and couldn’t find much out there. Lots written about front end noises and I’ve previously sorted my front end.

Rear creaking started this year with the cold weather. Sounds like a rubber creak/crunch when going over speed bumps at slow speed. 100% from the rear. When the rear tires hit the bump and the car goes “up”, I can hear a slight crunch. When the car comes “down” this sound is quite loud.

I have a 970.2 with air suspension. 72K kilometres (45K miles). Original shocks and struts but new air compressor (and relay and fuse) installed a few years ago. Air suspension is working fine with no codes or leaks. Tires are near new and I currently have my 20” winters on the car.

Thanks in advance!

 

Hi, same as front : sway bar bushings... but at the back.

 

Following up on this. Took the car to my trusted Porsche dealership. It took some time for them to find the source of the noise and they used “chassisears”. They diagnosed an issue with the rear shock absorbers. Specifically they found:

“Shock absorber piston is lightly contacting the upper shock body mount. Suspect inner bushing is worn on body mount.”

The fix they suggested is 2 rear shock absorbers if I can’t live with the noise. Their quote for this work is crazy! To be honest, they have actually recommended I leave things alone and deal with it if/when the shocks start leaking.


As with most Porsche enthusiasts, I’m not sure I can live with this noise. I'm considering DIY-ing it. I'm pretty handy and have a warm garage and good tools (no lift but have friend with a 2-post lift if needed). I suspect someone here has done a DIY on their rear shocks. Advice please! Also advice on sourcing replacement rear shocks? I have ordered from FCP Euro in the past and they carry Arnotts. Other options? Porsche OEM? FVD Brombacher?

Thanks in advance!
