i was driving down the highway today coming from school and at around 70mph i felt this pretty intense vibration coming from my gas pedal. this is something out my skill. could the drive shaft be unbalanced. or possibly the tcc sticking?

 

I'd change out the u joints first, do you feel it in your steering wheel?

 

not at all

 

U joints, mud on the inside of the rim possibly, low spot on a tire wearing front end parts. Coming from front or rear?

 

If he feels it in the pedal that usually means coming from the rear, so my first suspect would be u joints

 

Its the ujoints I had a cap come off mine today so in the morning I will be replacing the whole ujoint so damn excited but if the u joints is bad fix it asap cuz it could tear up the driveshaft

 

Every time somebody says that, it reminds me of this.
"You got mud in your tires".
"Let me ask you a question. How do you get mud into the tires?".

 

The cheapest thing to try would be pull the wheels off and have them balanced, also make sure there is no mud caked in there and will also give you a chance to shake down the suspension. A driveshaft issue would normally be at lower speeds.

 

Driveshaft issues don't show up till highway speeds check your ujoints

 

the u joints seem to be tight. i know front end is tight.im leading towards torque converter
