i've got a funky sound when i'm driving, i thought it was my axle or possibly wheel bearing, so i replaced both on the driver side.
but i still have a light grinding vibrating sound? could this be the intermediate shaft?
not sure how i can determine if it is or not. any ideas? thanks

little car info, not sure if it is relevent.

-car has 130k miles,
-passenger axle was replaced as well.
-new tires
-tie rods checked out okay
-car needs an alignment.
