Default Grinding noise while slowing down, whirring noise while speeding up

I have a 2004 PT Cruiser, Touring, about 130,000 KMs and I've had a transmission leak that took three visits to be fixed in the last six months.
Not sure if this is related to the leak, but the car has started to make a grinding noise when I drop below 40KM/H. It's not just brake related - if I don't brake and just slow down, it makes the same noise (but not as loud). When I brake from a high speed the sound is much louder.
When I accelerate, it makes a whirring noise until over 40 KM/H. There's no shaking and no other odd noises. It's fine at high speeds and is fine when I start it.

The noise is loud - it sounds as if I were driving over a snowbank or I'm dragging something.

Any ideas?

Thanks

Sounds like a wheel bearing. Try turning the wheel - if noise changes, it confirms it's a bearing.

Thanks quicksilver don -

The noise doesn't happen when I turn the wheel, only when I slow down or speed up. I took it on on the highway after the noise happened and did some turns at rather high speeds and no noise, until I got off the highway and slowed down below 40 KM/H.

Maybe a motor mount, some plastic supports, not too expensive
Mine did that too, took it to mechanic and turned out to be that thing

I'm betting wheel bearing. That is the way mine sounded too. By the time I changed it I had to replace the hub as well.
