I recently developed a rattling noise that appears to be coming from the
left wheel area. Its kind of high pitched rattle that I hear every time I go over
any type of imperfection in the road. I just replaced both front lower ball joints
and put on new tires. Any ideas might be lose?



Thanks! KJC

when i start the car there is a rattle seems like exhaust? but as soon as i am travelling more them 5mph its gone. Only at idling/VERY SLOW SLOW speed in 1st gear. Any tests/symptons people can advise me so i can pin point the EXACT cause?

thanks my friends :cheers

Cannon - it could be the brake pads are shaking around in the calipers - if the clips onthe calipers are worn or broken you will get a very metallic rattling noise especially over high impact type bumps - I had this problem and my mechanic sorted it by removing the pads and making them slightly longer and better fitting by smashing them with a copper hammer

Hope this helps

I think you are right about the noise. Is this something I can do pretty
easily myself? Or am I better to have an expert try it?

I am pretty convinced that smashing anything with a hammer is do-able by anyone!

Removing the brake pads is fairly str8 forward - there are many posts on here if you are unsure

Then all you need do is see if they wiggle about in the calipers - if there is any movement they will rattle BADLY when you go over a bump

If you are unsure - remove the wheel and tap carefully with a hammer around the pads, arms etc to see if you can re-create the rattle you have described

If you do make the pads slightly better fitting make sure they dont just wedge in hard - you will only need to make them a millimetre longer so dont go mad with the hammer smashing

cannon- i had kinda the same problem , but for me it was the mud flap that broke in front of the wheel and hence made the noise.


mstar- check your heatshield for ur cat, just got mine welded back on and mine made the sound at idle too!!!
