I would not try running the car through the gears with the car up on a jack.
This is very dangerous!

If swapping tires front to rear does not change the sound, then the tire and
wheels become less likely causes.

The wheel bearing would be the next most likely cause, but since it was
changed and the sound is still there, I'd check the constant velocity (CV)
joints, rack ends/tie rods, and ball joints. This stuff should have been
checked when the wheel bearing was replaced, but it's possible they were not
checked.

This is very dangerous!
R: Gotcha, makes sense...

R: Yeah, seems to makes sense, two sets of tires to be bad doesn't seem
right. Though like you said, you would of thought toyota would of
check the other area especially when they did an alignment.

Thanks again

If the dealership did an alignment, then they definitely should have checked
the rack end/tie rods/ball joints.

The CV joint may or may not have been checked out.

A rebalance whould detect a bent wheel or defective tire.

Could have just been a coincidence, but I'd still be suspicious. Is the
noise the same under power and when coasting?

Noises can be hard to diagnosis. It could be that the noise is transmitted
into the car by the same path, no matter where it is actually generated. You
mentioned you also had a vibration. Did that change when you swapped the
wheels around? What do you mean when you say one of the wheels was a little
off? The actaul metal wheel should not be a little off. Sometimes the tire
sidewall is not completely true, although the tread surface should be.

Not necesarrily. It depends on what is wrong. Does the noise change when you
turn the wheel?

I went back to the tire place and asked they they rebalance all tires
and do another check for me before I bring it back to Toyota, they did,
no problems detected, I believe I can rule out the tires.

Noise is the same, I have a standard, put the clutch in at 70mph and
engine idling, noise is the same.

No change with a rotation, definitely something in the front end.

It's weird, it does change a little with a turn but not always. Seems
to be heard the best at 40-45 mph I guess it has toyota stumped too
since they're not sure where it is coming from. They changed the right
front wheel bearing Monday, I had the wheels rebalanced on Weds
morning and then back to toyota to take another look. The tech came
out and took a ride with me, he could hear it, said he checked both
bearing when he did the work on Monday but they don't always show a
problem without a load on them. It seems like the sound is now coming
from the left side, maybe the other bearing I said to him. He said
toyota wont just let us change both bearing unless we are sure that is
the problem. He then took out his manager that use to work on these
cars, the manager came back in and told me all he heard was tire noise.
I suspect what they are saying is they aren't going to fix it until it
is louder and they can determine for sure what the problem is, what a
pain... Appreciate all your advice.
