i have a 94 camry it was shaking but it was the axel and i changed it but another ?
can i put in a v6 in a 94 camry LE 4 cylinder, what do i need to change for it to fit ???

You really don't need to change much in order for the engine to "fit". Although you will have to practically redo your entire suspension to withstand the weight of the V6. As long as you get the engine, and all of the suspension parts from a V6 Camry of the same year, you'll be all set to go.

Save yourself time money and headaches....

Buy a Camry with a V6 already in it from factory!
