Vibs While Accelerating (not the normal vibs)

So i just had my truck at toyota the other day for a oil change. They checked a noise my truck was making while i had it there and determined it was the CAT and replaced it. So far, no more noises.....

Well the night after getting truck back from them, my truck starting to have weird vibs throughout the whole truck anytime the truck is under load (acceleration). As soon as i take my foot off the gas, it goes away.

Before taking my truck back down there, i was wondering if anybody else has had any issues like this and could share your info



Thanks!

 

Exhaust leak?

 

check all your heat shields and exhaush mounting points for starters.
then check driveshaft, u joints , ect

 

turns out the u joint was failing so toyota replaced it and the driveshaft under warranty.
