yet another thread about vibration

I've done multiple searches on here to figure out what my problem might be and I'm very confused. I am experiencing vibrations when accelerating between 20 and about 65. Really bad at 30+. However, when I let off the gas, it stops. I feel it in the seat and steering wheel. I've always heard a moaning sound when accelerating below 30, but the vibes just started.

After doing searches, I can't figure if it is a driveshaft issue, trans mount, tires, or springs. I have a '07 TRD Sport access cab with 86,000 miles.

Any help in diagnosis would be greatly appreciated. Thanks.

 

Start by removing the driveshaft to check your universal joints and the condition of your carrier bearing . If i had to guess , it sure sounds like a tire issue .

Thanks for your response. It does feel like a tire issue. But, only on acceleration. When I let off the gas, it stops. I think if it were a tire problem, it would continue when I let off the gas. It feels as if I'm driving on those rumble strips on the side of the highway.

 

***UPDATE***

It was 2 bad u-joints. Luckily, a cheap fix. Center bearing was fine. Thanks.
