Car shakes violently when accelerating. on 2004 Toyota Camry

It usually starts after the car has been on the road for a while, maybe after 20 minutes. At first I believed it was due to my bad tires but all four has been replaced and I got an alignment after replacing the tires. The shaking is still there. It's really noticeable when climbing a small hill. It feels like something with the suspension. Axles maybe? Any ideas for the cause of shaking? Cost of repair? BTW, I have 240,000 mile on the car.
Thanks!

Check,HAVE AXLES CHECKED FOR INNER TRIPOD WEAR.THEN ALL ENG. AND TRANS.MOYNTS.
MOST LIKELY SUSPECT IS AXLES!
Thanks! If it is the axles, how much to replace? Thinking about replacing the car if it's too much. I have lots of miles on this car although it's been great until now.
ck axles or motor mounts or scan misfire data
Is replacing the axles expensive for the 2004 camry? With so many miles on it, I'm wondering if it's worth it.
REMAN.AXLES ARE VERY REASONABLE AND JOB IS NOT LABOR INTENSEIVE.
YES YOUR CAR IS WORTH THE REPAIR. A LOT MORE RUNNING LEFT IN
THIS TOY.
