2nd Gen Non-Engine/Transmission Friend's 2000 V10 auto has a "wha wha wha"

[TPCDrafting]

Rode in a friends 2000 2500 QC Short bed V10 Auto 4x4 last night and it is making a "wha wha" noise when rolling. It's more noticible at low speeds, but it's frequency speeds as he accellerated. It does it weather he was on the go pedal or break pedal. Can't tell which side it was, plus I could feel it in my feet on the floor board. He just bought this truck a few months ago at 100k miles. It's a grindy kind of wha wha sound, so I thought it might be a wheel bearing going bad. Another thought was a front disk that is badly warped. Any other thoughts??

Noise

To me it sounds like it might be the U joints,when the get ready to go out. Eric

Thanks, You mean the ones at the ends of the front axle?

Either U joints or Center Bearing. Heck mine went at 24K completely.

I think it's the u-joints too. My truck is doing the same thing now. Going to get new u-joints today.
