What would make the Toyota shake? on 2006 Toyota Camry

it is not the motor mounts. We also had a new front end drive axle replaced. It only shakes when foot is on the gas - quits when you let go. Tried putting in sea foam to clean injectors. Still shakes from 0 to 60 and after that smooth sailing!

inner cv joints are common failure. did you change both axles??

We only changed the front wheel axle. I didn't consider cv joints but it is certainly something I will check out. Thank you so much! I want my Camry back!
