Default Vibration, rumbling noise at 40 mph

Hi I'm having a problem while driving at 40 mph. If I'm below or under 40 it goes away. The noise feels like a rumbling, bouncing noise( like it's skipping a beat). Especially when I slow down on rough roads. I can hear the noise coming from the front passenger side.

I've search here and other forums and the possibilities are cv joints, bearing and control arms. But I don't want be a part changer. I want to pin point where the problem is. If anybody have this similar problem, could you please chime in. Any help would be awesome. Thanks for reading

Another symptom that can confirm a bad wheel bearing before putting it on jack stands;
When you're on speed(40-60mph) then do a turn, either left or right, and the noise/sound disappears. This means that by removing the weight on one side/bad bearing, the sound disappears or faints.

If still can't figure out then;
Put it on jack stands or lift. Then for each wheel/tire, try to move it by leaning at 1-2 o'clock, 6-7 o'clock, 10-11 o'clock or 5-4 o'clock. The wheel/tire/hub is not supposed to budge at all, which ever wheel budges would be the one with a bad bearing.

Yes, when I do make turns, it goes away. But will jack it up to check. I know in your other thread you been doing maintenance on it. Did you change out the bearing? Was it hard? Sorry for questions but I know I'll be expecting a thousand dollar quote.. :/

Do you have aftermarket wheels? Something I ran into lately was lack of hub rings.

Yeah, I do have aftermarket rims on. And have the hub centric rings. But I did check and it's my bearing going out. Freaking sucks
