tap tap tap what the hell is that

just had a thought cuppa ,could it be that someone has changed or had a look at the speaker in door . Maybe they didn't fix the wire back properly . Or it could be a damaged air conditioning filter.

Sounds like a loose wire knocking on something when I go over rough road, I thought that the speaker wire was the most likely, but not so. It seems to be around that area though. Have had my wife trying to locate as I drive, but no success. Thought I'd found it when I had an inner wheelguard cover off, there was a prime candidate wire, wrapped a bit of foam around & was confident I'd finally found the cause, but again not so.

I definatly now think its the stones in sill thing

Try removing the mud flaps and see what happens.

Changed mud flaps (& mountings) when I had the new tyres put on recently. The tapping precedes the wheel change.

Alf when you say in the sills do you mean underneath the strip of plastic which pulls off?

Cuppa

Sway bar links?

If you take the vent out from behind the passenger seat outside of vehicle between pod and cab body there are two one on either side It is a little hard as gap between two is slight , they are fixed with 4 Philips head screws . Completely remove vents to expose void between inner and outer skin of main body , put your hand inside and have a feel around there will be all sorts of crap down there . Now hold up the vent next to your ear and give it a shake the four flaps made out of vinyl plastic slapping on the rigid plastic outer casing sound just like a wire tapping on metal . The two things I did was vacume out the void between the skins on main body and I then placed foam in each of the four cavities between the vinyl flaps and outer slat like vents locking the flaps against inner frame. my patrol is now quiet as a mouse . Hope this helps you as it did me cuppa Alf ps As I said my ute has only done 15000 km so god knows what a ute wich has done 100,000 ks has in there pps go for a drive with the vent out see how it sounds then

Something in or on tyre tread?
