Whistling noise when driving on freeway

My Prado is less than two weeks old. No bull bar or snorkel yet. I notice a slight whistle at around 80kph. I have tried changing revs so it is not from the engine. It is very faint. I will check with the dealer when it go's in for 1000km service.

All 4WDrives should make noise, if they didn't they be a "car" And the more noise they make means you have more accessories and mods.

Do the roof racks have any open channels, were the feet slide along the bar they should have rubber inserts either side to fill the gap, if not that is were your whistle is coming from.

Hi hutch, just checked the roof racks, there I no rubbery covering the slid channels for the legs. Is the rubber meant to come with the roof racks? or are the channels exposed by default?

Is it a diesel, as it could be turbo whistle.
It can also come from the exhaust, if there is just the slightest bit of mig wire protruding into the exhaust, it will whistle.

Mine does this as well. It is wind noise on mine as when you put your foot on the clutch it doesn't change. My problem it changes at what speed it makes a noise. I have been hunting for about 2 years now and can't find it.
When we first put the snorkle on we had an issue of there was a gap between the head and grill which did whistle badly. Mastic between the two sorted that out.

The rubber should have come with the racks, that channel is were the whistle will come from, put some rubber in and u will be amazed at the change.
