First problem....Noises when steering at low speed

[Frutti_pig]

Think i have encountered my first problem!

Help/advise needed.

While driving at parking speed...turning the wheel past quarter turn evokes an unsmooth ride from from front wheels and a clunk type noise from front of car, definitely feels like its coming from the steering. Car is on Porsche 20" rims, front tyres are contis and just about had it.

It was fine when I parked it up the night before!!


My first thought was wheel bearing...but I'm not the expert. Any ideas guys..

is it a 4 wheel drive? if so clunking from front is normal when cold - especially in reverse

Are the wheel nuts still tight?
Someone may have been trying to pinch the wheels overnight....

You've not said what car it is? If it's a Boxster then the clunking is normal, especially in reverse. IIRC it's to do with the front geometry settings due to unequal length wishbones, something to do with the Ackerman effect.

Hello John

In my experience wide low profile tyres have a tendency to slide and judder sideways when manoeuvring when both the tyres and the ground are cold, so there may be nothing wrong at all.

Hi Guys,

Thanks for the response. Its a 03 Cayenne. It is "hopping" when on lock, likemy old 4x4 used to....however there is also a metal clunk and bit of squeal/groan when trying to turn at slow speed. It does not need to be on full lock, anything from half a turn on wheel instigates the noise etc..

Hope that makes a little more sense...........

I know its a PIG but its not supposed to actually squeal!!! []

Well I thought I'd give u all an update. Car has spent the last 2 days with RLR In thornaby - had the major 48k service done as well as the boot and glass rear hinges/hydraulic replace.

Clunking notice from front end was deemed to be a missing engine mount bolt!!

I've not driven it yet, but look forward to putting some miles on it over the weekend

Same message on the Cayenne forum too. But maybe a little closure...

Had my piggy on the ramp and checked over again by head tech and gearbox guy. Nothing loose, nothing perished and nothing missing or broken!!

But Its definitely their intermittently and they have heard it happen once. On Rocking (I mean turning by hand) the front center drive shaft, it obviuosly turns the wheels but hey presto a very similar noise can be replicated - so final analysis is slight wear and tear in the joints which when hot after a decent run seems to show up....but only sometimes. The techs said they would not advise to go looking for something by replacing parts. So I'm kinda happier now!!

BTW Porsche across the country are having a open workshop for all Cayennes to be given the once over checkup by one of their trained technicians - Early March I believe the 4th.

Anyone else having or had these noises??

What was your outcome?
