Strange Handling Problem

[windsurfnut]

I have a 2004 Cayenne S. No air suspension.

I'm finding the vehicle recently somewhat unstable. Under normal driving conditions the vehicle appears to drive normally, however, when driving aggressively, on higher speed sweepers and tight corners/swtichbacks, the front end will all of a sudden wash out. Like I hit Ice or something.

Tires are Pirelli Scorpion snow and ice, roads are clear of snow now, with a little bit of sand in some spots.

Any ideas? It's really odd.

Do you mean under steer? Are the tire pressures correct?

[windsurfnut]

Yes, Understeer, but it happens quickly, like low tire pressure, but the pressures are correct.

I would do the test over again with OEM rims equipped with Porsche approved tyres, it can save you money and time.

While I don't disagree, I've got 10,000km on that set up with great handling, yet recently it started doing this odd behaviour.

The tires could be crap and are now losing traction, however, they have good tread and roads were dry.

Maybe an alignment issue?

Have the front suspension components inspected. Perhaps you have a failing control arm bushing and the loading is causing a alignment issue.

Just a thought, but I had my Cardon shaft replace 3 weeks ago. Would there be any affliation to the problem, perhaps with suspension components that would have been removed for installation of the shaft?

The more I try to duplicate the issue, the more I am pointing a finger to the rear suspension. The vehicle will suddenly sway when banked over in a good offramp sweeper. Rear sway bar perhaps?
