Not a Leak for Porsche
This bulletin applies to Porsche 9x1 sportscars, 2012 to present. Suspension bushings appear to be leaking. When suspension bushings are installed, an assembly lubricant is used. It is possible that over time this lube will weep and appear to be a leak from a bushing that is not hydraulic. Verify that fluid is not leaking from other components such as shocks or struts and clean off the weeping lube. The only hydraulic bushing on 9x1 vehicles is in the lower control arm of the front suspension.
The only hydraulic bushing is in the front suspension lower control arm.
