2006 2wd vibration

i have a 06 4 cyl 2wd basic Tacoma. It has 69000 miles on it. Over the last couple hundred miles I have noticed a dull vibration that I can feel through my gas pedal foot.

It happen during acceleration between 35 and 60mph. It does not vibrate accelerating at lower or high speeds.

It isn't the tires because it only happens when my foot is in the gas. When I level out at 55 or 60 the vibration slows down but does not completely go away.

Any ideas where to start looking for this? Timing chain? Transmission ? I don't have a clue.

If I haven't explained this well, let me know if u need more information

Thanks.

 

Check the driveshaft and U-joints... that's all I can think of right now.

 

As @DGXR said check the u-joints. It could also be that the center support bearing needs to be replaced.

 

Not a legit eliminator. It might not be a balance issue, but a broken belt issue.

Best way is to rotate tires front to rear and see if anything changes.

It's free, worth a shot.
