Car: 08' Honda Accord Ex, 2.4L

Problem: Once the car speeds up to about 10mph it starts to make a "thuh thuh thuh" sound from the front left side of the car, it doesn't really vibrate hard at all, but once I'm going faster and start merging left or go down a (left) curved road the sound and vibration will intensify, if I merge right the problem will almost be non existent unless if I make a hard right then it makes the sound again.

What I've checked or fixed/replaced: I've changed the brake pads and rotors (thinking maybe the rotors were warped) I also cleaned the brake caliper brackets and sliding pins (I know its ideal when changing the brakes) . I checked the axles and neither seem to have excessive play or any tears in the boots. I did replace the tires, they were at 2/32nds. I checked the play on the wheel bearings (hands on 12 o'clock and 6 o'clock of the wheel and shake up and down) there's no play that I could feel.

I don't wanna keep throwing money at this problem any help would be greatly appreciated.

Could it be the wheel bearing even if there's no play?

yes... even if there is no play. bearing runout is measured in thousandths of an inch, you can not visually see that normally.

it could also be something else.

This sounds like a wheel bearing. I've run into the issue where it was making noise but felt tight.

Also check the differential bearings where the axle mates to the transmission. I just had this issue with my 96 Accord which resulted in me replacing the transmission.

I'll change the wheel bearing cause that's what the cheapest fix would be, I got a press at work.

Yeah, just to confirm what everyone else has said it sounds like wheel bearing. Checking for play on the wheel while the car is lifted would indicate bad ball joints.

It was the bearing, removed it and it fell apart, one of the races was pitted pretty bad, put a new one in and the car drives so smoothly, i catch myself speeding now cause the noise/vibration doesn't remind me to slow down haha. Thanks for the input guys, appreciate it.
