Can bad motor mounts cause hard shifting?
Hard shifting is certainly a symptom of bad motor mount(s). And especially with an auto transmission. The likely suspect is the motor mount located in the rear of the engine bay; this mount takes the brunt of the force when the engine torques from accelerating and shifting.

What to do about vibration in Toyota Sienna?
While I got over 200,000 miles on my 2006 Limited before having to replace the passenger side axle, there is no set lifespan for these things. One test is to turn your front wheels as far to one side as possible and slowly drive the vehicle forward then backward. Repeat with the front wheels turned as far as possible in the opposite direction.

Why does my Toyota Sienna make a humming noise?
Bad wheel bearings will make a loud humming noise, they have to be really bad before they start vibrating. Give it the ol’ bounce test to check out the struts, try to move the control arm, tie rod, ball joints with the wheels off the ground to test out the rest of the front end.
Where is the cVj joint on a Toyota Sienna?
Toyota uses a rather unique design on the passenger side axle where the intermediate joint is NOT a cvj (constant velocity joint). They use a much simpler joint design for it and the test I describe above will not work for that joint.
