ok the bumping. it seems at 60 to 68 mph like you are briving over a rumble strip but not that pronounced. It is a slight up constant at that speed bumping. The cv'* look good no rips leaks or whatever. Balljoints should NOT make that happen but they are tight as are the tie rods. The only thing I can see doing that is a cv shaft either worn and chucking up and down or a bad tire or rim which I have eliminated already.. What process needs to be done to change out a cv ? Do you need to remove tie rod or ball joint ? I know rotor and caliper but what else ?
