It could be something as simple as unbalanced tires. Either have then balanced or rotate then by putting the front tires on the back and the back tires on front. If the vibration is now in back, the problem is that the tires need to be balanced.
If that doesn't cure the problem, call a local alignment shop to see if they will do free front end inspections. When you fiind one have them to check it for you; but DO NOT PURCHASE ANY PARTS until you post the result of the inspection here for more advice.
