Well, think about it. Its caused by caster angle. Without caster angle there is no force trying to make the wheel go straight and so you lose all steering feel. Kind of one of the biggies a 911 has historically been known for. Also the car will be darty and unstable, not wanting to go straight and stable at high speed. The more you minimize caster angle the more you minimize steering feel and make the car difficult to drive at speed. Or it could be reduced by going to a tire with a lot more squirm. Smaller tread blocks. Higher profile. Not as wide. Softer compound. Winter tires, basically, or touring or all-season tires. Another thing they could do is use softer suspension bushings to dampen it out. Are you beginning to see a pattern here? Each and every one of these things is the OPPOSITE of what you want in a high performance drivers car like a 911.
So yeah, Porsche could easily solve this "problem". All they have to do is make something other than a 911.
What? Friction modifier? Warming up car? What are you talking about?
This is NOT an AWD issue. Happens on the rear wheel drive cars too.
really, I never heard of it on rwd cars. It happened on my awd only. It was a grinding and groaning sound coming from the front and rear differentials. I put friction modifier in the trans and diff and that minimize the sound a lot. Also, this happened only at cold start and if the car is warmed up more (3-5 min), that helps too.
we maybe talking abt a different sound though. But just sharing my experience
I am beyond tired and bored. This topic has a multitude of posts (over many years) explaining it. Why do does anyone give their time and energy to explain a topic over, over and over again after the OP with a legitimate question is guided to the answers that they refuse to research/accept? When behavior like this is accepted and continues, it will do nothing but turn those away with something to contribute. Everyone who wants this board to continue to be a productive source of information puts it in jeopardy with this behavior.
