Whoosh Sound From Left Front Wheel

You and James hit my 2 thoughts.
Air ride, Hydroboost.
My Tahoe has hydroboost.

Interesting. I thought that was a Suburban/Yukon XL/ESV-only thing.

My 2005 Yukon Denali does this same exact whoosh noise to. I figured it was hydroboost noise. Seems to be coming from that area. Essentially directly behind my instrument cluster on the other side of the firewall.

My Tahoe has hydroboost.

Likewise, my '04 Tahoe has factory hydroboost, RPO JH2.

Sounds like a restriction in a line somewhere, hydro boost or power steering. Are all your hoses good with no kinks? Sometimes a hose can have a too- sharp bend that doesn’t look like anything but the inside is restricted. Then once pressure is up the sound goes away.

Could you post a video of the sound?

My '06 Tahoe had hydro boost.

Could it be the purge of your air ride suspension? They bleed off a short time after start up, could coincide with your routine of departure.

It did not come equipped with air ride suspension...

I now leaning towards something brake related and here is why...Traffic was moving pretty good and it came to a super fast stop and that right front sounded horrible when braking to stop... Then just driving a little bit more seemed way off with weird sounds... So need to check that out.... Just diminished a Total Nightmare... Passenger side blend door actuator that is the one buried in the dash... I will do a post on it and whoever designed it and put it there I guess it looked good on paper and not thought given but to let the dealerships make a fortune changing it....

Collapsed brake line?

I did that actuator, not fun. I was able to get the right side of the dash to pry up just enough to get to it. Still a good 2 hour job. The SM says to remove the whole dash cage assy. which is more like 6 hours.
