Vibration from right front end

have the front end checked by an accredited front end specialist shop
could be the lower control arm bushes torn

tires out of balance or showing threads

You obviously have a suspention problem that needs to be found. If it's a 4wd, the u-bolts to the front end can get loosened and cause the front to shake. the bushings that set the front end in alignment can also be wearing and not be holding the way they should. I'd take it either to a good suspention shop or the dealer and let them look at it.

If the noise gets louder around corners while the 4WD is being used the Constant Velocity Universal joint is worn out, if not the truck probably needs stabilizer link rods they are fairly inexpensive but the CVU joints are not.

This could be a loose hub bearing causing the hub to move in and out .When accelerating the weight shift will be less on the front wheels so the hub may be moving in and out during this .Have this checked soon :)

Are the tires balanced? Did they use stick on weights, if so? If this holds true, see if there is a mark on the wheel, where a weight has flown off.

How about the front end alignment, and condition of the tires. Sometimes a belt slips in the tire. This is hard to see, but can be found by sliding your hand around the tire, and you will feel a bulge to one side. (Use caution, as there's no telling what may be stuck in your tire/s, and you can damage your hand or fingers. I realize how that sounds. One has to use finesse, when checking one's tires, with this method)

HAVE THE TIRES BALANCED AND CHECKED FOR SEPARATION

Have the balance checked on the tires.

We're on our second Sedona and have had this problem on both. In our case it was the front brake rotors. The dealer told me that they're not made thick enough to handle heat loads. They are super-sensitive to heating and warp easily.

With my Sedonas the pads were not retracting completely, sometimes dragging on the rotors (not enough to notice this while driving) causing them to heat even when the brakes were not being applied and causing this front end shaking in the steering wheel when braking. When it got worse, the brake pedal would vibrate too. When we would take it up the mountains the long braking periods on the downslopes would make it much worse as the rotors heated up. The dealership had them machined but the issue persisted and ended up replacing the front rotors.

Replacing rotors is not a difficult task if you're mechanically-inclined and have the right tools. I've done it on many vehicles (though not my Sedonas as they were warranty jobs) and it's usually less expensive to replace them with new ones from your parts store than to have a brake shop work on them.

Hope this helps.
