Vibration when accelerating

I have an 08 crewmax, when accelerating I have a vibration. Would this be the cause?

 

Causes can vary, but if your truck is lifted more than 2.5 inches, there's a chance the angle of the draft shaft changed up to a point that it induces vibration over certain speeds.

 

Serious question, or sarcasm? Because the answer would be “Absolutely yes” or “Nah, it’s fine”, respectively.

Greasing a wee bit more often would certainly increase the u-joint life.

 

If you lifted the rear at all, even an inch, it may need a carrier bearing drop installed. Tundras are finicky when lifting the rear, some trucks need the drop kit, others dont.

Lube your driveline zerks.

Do the above first and if you still have an issue report back.

 

That U-joint is completely shot. If the others have seen the same amount of grease, they’re likely not too far off of that. Zero point to greasing the pictured u-joint unless it’s more fun to replace when it’s all greasy.
