Vibration when accelerating

I have a 2007 Toyota Tacoma Access Cab 2WD automatic 4-cyl with 88,000 miles. It vibrates when accelerating, which can be felt through the steering wheel and dash. It does not vibrate when coasting, braking or revving engine when in park, only during acceleration. Any help here is much appreciated. Thanks.

 

Drive shaft?

Could actually be your universal joint or your carrier bearings..

The second link helped and u joints seem to be the problem, because when I grip the drive-shaft and try and turn it, there is play there and apparently there shouldn't be?

 

Is there any way to tell for sure?

 

The issue has been resolved. it was the front u-joint. Thanks for the assistance!
