Rattling metal noise coming from hood?

Postby Iggy » Mon Jul 27, 2015 10:54 am

I just noticed a rattling metal noise coming from the hood I think? It makes that noise when I drive the car along rough roads and even when just crusing at low speeds. What can I do to identify where the noose is coming from?

My young bloke came to me with a report of a rattle in his Outback.
I took one look at his car and asked him to remove everything out of his car (read rubbish) as a starting point.
So, first remove everything out from the front of the car (glovebox, cubby pod, etc) and then go searching.
Remove everything that is not bolted down and could generate vibrations.

I had an annoying dash rattle in my Spec-B. Eventually tracked it down to a worn bush in the gear shifter linkages.
NVH issues are a cow to try and diagnose and unwanted materials only make the job harder.

Check where your bonnet closes, front left/right corners, I believe there should be some height adjustable rubber bonnet stoppers.

Another Gen 5 owner had a rattling bonnet just like what you describe, and the fix was to raise the height of the rubber stopper.

Hopefully that's all it is, a simple fix!
