Default Mystery Sound While Moving

99 XJ Classic with 4.0/aw4/np231 w/103,000 miles. Video is attached. I'm wondering if anyone has heard this before. It's a subtle 'whoosh', or like an ocean wave, seems to be coming from front tunnel on driver's side. This only happens when vehicle is moving. I hadn't heard this in the 4 other Jeeps that I've owned. I'd love to hear any thoughts on what it could be. Thanks in advance!

Just realized that I can’t watch it on my iPad either. I’ll find a way to repost. But yeah, something in tc, front ds, diff, or brakes. Ds would be a good place to start

Could it be coolant rushing through the heater core?

I couldn't really hear anything but listen down by the pedals. It could be the brake booster leaking. I've had that happen and it's a constant whoosh/hiss.
