Hey guys,

Just a quick update for you. I took the truck into the service department today and they swapped my wheels for 20" Bridgestones from a '08 Limited Tundra. Took it for a test drive and it made no difference. Same noise and vibration.

So the wheels and tires are officially ruled out of the equation.

The tech that was with me thinks it might be a bad bearing. They're going to order up a bearing to get it in stock. Then I will drop my truck off for the day with them and they will do further testing. If a bearing is indeed bad, they will have the replacement ready to go.

But, the fact that the noise is very subdued in 4WD has me concerned in that I believe a bad bearing would cause noise all the time.

In the end, my dealer is doing a good job and I'm confident they will find the problem. It's taking time, but I'm a very patient guy as long as I know they will work on it until its fixed. It appears that is what they intend to do.
