Werid Rattling noise?

jaackla · 13 Jun 2017 at 13:57

Past 2 weeks while driving i hear a very loud rattling noise its not consistent it comes and goes every few seconds, all my gears work fine too and the car drives fine but its never done this before. It sounds kinda metaly like something is loose but im not sure, its hard to hear where its coming from but when i have people in the car they all think it sounds like its coming from the front passenger side wheel, but when im driving it sounds like it could be at the back or over my side, i took it to 1 garage and they couldnt find nothing

Does it make the noise immediately and throughout your drive?

Not as soon as i start my engine on but it can take anywhere from 30 second -5 mins to start, normally when going over a bump or a rough road surface that really keeps it in and it stays throughout the drive

What car is it?

Im thinking heatshield.

Could be a snapped coil from the spring jiggling about in the spring cup. You can try tapping various components in the front suspension with something metal until you find the same sound which is how I found the problem above when I had a similar unidentified noise.

Given it's a rattle it could really just be a case of tapping components until something matches. I'd start underneath. Then move to suspension. Check any brake disc backing plates. Then engine bay.

As above check all heat shields first, then give the disc backing plates a good wiggle, check springs before moving on to just tapping stuff both with load on /off each wheel

If it is a heat shield it will get a lot worse, so you will know

Normally the fix it just welding it back in place.
