Knocking sound from the fender when making turn

[peterjaw]

Hi guys,
Recently, my car has weird knocking sound from the fender of the front tyre area.

When I make slow but sharp turn, like turning righ on a cross road or turning into the parking garage, if the road surface is bad or has pithole then I hear sort of knocking sound from the fender area; especially from the outter tyre area.

I don't always hear this but quite often. The sound is like a small thing hit the fender.

Does anyone have such an ecperience? Does anyone know what is this?

I hear it all the time too. It sounds like someone is throwing a rock at your car right ? It happens a lot. I'm wondering what it is. It happens to me no matter if I'm turning or not. I'd be curious to find out what it is.

I heard it once from the rear right fender. At first I thought little stone chips were being thrown at by the car in the front or the wind, but that seemed unlikely.
I was making a left turn on an uneven surface.

What size are your wheels, could be rubbing...

Exactly like what you said, Lakai. But I can't always reproduce the same situation so I don't know how to describe to the dealer.

If anybody find out how to reproduce this, please share with us so that I can show to the dealer and ask them.

By the way, I am using 18" wheel,the tyre are 255/55/R18, so it can't be rubbing.

I have 19" sports package tires. The sound is very random. It happens quite often and even then I am unable to determine what causes it. It really sounds more like a rock hitting my winshield than the car. The sound comes from the Front Passenger side somewhere.

Has any of you gone to the dealer for this problem yet?

I think I'm having the same sound, but coming from the back. I thought it might be either the suspension or body flex.

Not sure if it's the same thing or not. But I can reproduce mine at will.

I still have yet to bring it in. I now have a couple of little bugs to shake down. Well, a creeky sounding drivers seat when adjusting the bottom, the clunk, and I need to tint the front windows.
