Left wheel bearing or either CV axle,(left or right) Axles usually make the vibration turn left or right. Bearings will get loader turning. When you turn right, the pressure is on the left side.

No surprise at all! Common problem which has been discussed several times on this site.
Basically.....tail light(s) plugs (Pig Tails) were sub-standard and cannot stand the heat of the bulbs. Pull out hear tail light fixtures, remove bulbs from recepticals and check for melting plastic, usually between the black wire (hot wire) and one or more colored wires. If so, cut out old Pig Tail, get a replacement Pig Tail, soder it in (I think about 6 wires), and use electrical shrink wrap around sodered joint, install new bulbs using Di-electric grease in the socket. Test before reinstalling light fixture.

The poster also mentioned something I forgot; use some kind of grease in the sockets any time you have reason to access them.
The dielectric grease he mentioned is best but if you can't find (it is and electronic item, rather than electrical), even petroleum jelly will afford some protection.
I use it on battery clamps and it helps ****** the typical corrosion.
Since most cars use the chassis for ground, even the fasteners that hold in lighting assemblies can lose contact so I always loosen, then retighten them, to ensure decent ground contact.
Check too for corrosion in the light sockets themselves.
Dunno why it is so tough to seal a compartment but our US manufacturers can't seem to get it right.

Had similar problem with 2003 Dodge GC. Replaced the parts you mention + rack & pinion, then to fix the now noticable whining noise, replaced power steering pump and pulley. Fortunately was under an extended warrentee at 46k miles.

Remove the wheel, remove the hub nut, remove the brake caliper and rotor, put your socket and extension through the hub flange onto the bearing retainer bolts, undo them, release the abs sensor connector if it has it, remove the bearing and hub flange as an assembly, put the new one on and go backwards from here. Torque the hub nut to 180 ft/lbs, your done.
SOURCE: Rear differential / axle noise and vibration.
A drive shaft that has lost a balancing weight will vibrate between 40 and 50 mph. If not corrected this could damage the input shaft bearing and seal on the differential causing oil leakage. Differentials are fairly indestructible but if run without oil will fail.
As for the front end you should never run the 4wd on dry pavement. The front differential is a posi traction unit that will turn both wheels at the same rate unlike the rear diff that will allow the inner wheel to turn slower than the outer on turns.
SOURCE: winding noise and vibration when driving on front right tire
you could have more than one problem the vibration accelrating maybe an inner cv joint ,if you just had the tires replace and an aligment done they should have checked the front end for worn out ball joint and tierods but the wheel bearing may not have any movment but can still make noise
