05 camry SE 2.4L. while driving i feel a vibration under my feet.

If the noise gets worse making a right turn, then goes away or close on a left turn. It is a wheel bearing. If it an engine mount. Put a jack under it and lift the engine slightly. If the vibration goes away. I suggest you replace all the other mounts.

it could be center bearing, if its going bad it can also cause a vibration, make sure you have sufficient fluid in the diff as well, you can also get a noise and vibration from collapsed motor or trans mounts

could be tires need balancing or front end alinement

Get the engine mounts checked. A bad mount may allow part of the engine to lie on a body or frame part, allowing engine vibrations to become very loud. Torquing of the engine (under load) can cause the same type problems.

check and test hubs and c/v axles

You need wheel bearings.. One for sure maybe 2. Do you feel it in the steering wheel or floor? The floor usually means rear and the steering wheel usually means front. Hope this helps. It should change pitch when you drive left to right at a steady speed. :-) Cobra

I'm thinking tires. Have the balance
checked.

If the wheel is in balance and there is no other signs of what is causing the vibration than yes that cv joint should be chk. Is the strut ok? might want to chk. that too.

Jack up the front end and put stands under it and block rear wheels. Look at axle boots and see if they are cracked. Try turning wheel back and forth sharply and see if you can hear any clicking. Problem could be outer axle joints. If the boots are cracked or you hear a clicking noise you will have to replace the axle. The axle and boot come as a complete unit. Please let me know what you find out.

front wheel drive? may not be the enging may be CV joints or wheel bearing,
