2004 4x4 front driver side vibration.

[cm644]

Hi i have a heavy vibration coming from what seems like the drivers side front tire. It almost starts immediately as a low rumble but as i accelerate the rumble turns into a much more accelerated vibration. Its very noticeable around 35-55 and goes away as i verr right or turn right. I was told it might be the bearings and i checked them and everything seemed fine no weird feeling spinning the hub. I was wondering if it could be a unbalanced tire, I noticed the front drivers side tire has worn a little on the inside but tread on the outside is still in great shape. or maybe an alignment . I just want an idea so im not taking it to a mechanic blindsided as the holidays are here. Thank you very much.

Any help would be much appreciated as im driving from ga to ct on fri and my husband is in the military so i have no clue about any of this. Thank you.

From what I've been reading on these forums, just because the usual bearing test doesn't show any play in the bearings, they could still be bad.
