I've got a 2005 Sedona (107,000 miles). The car shakes when I accelerate especially going up a hill or anytime it's under load. I figured it was the plugs/coils/plug wires, so I swapped them out.....but it's still there. Then I read a couple posts on here like this:

and so I decided to look into swapping out the CV shafts. But Should I replace both? Or is it ok to just replace one?
