CV's on their way out will usually make a clicking or clacking sound. You can test for it by getting in a big parking lot, turn the steering wheel to the stops, then drive the vehicle in a circle, first one way, then the other- ever with the wheel to the stops. This will work most of the time, though not always. Then check the CV bolt torque -- again. One thing that can give a false warning of iminent CV failure is two or more bolts being loose, while the rest are tight. The CV will move just enough to pop the vac of the CV against the face it normally is flush against. This will make a clicking or popping sound. Vibration at high speed is usually something else, most notable possibility is tread separation. Pull the suspected tire and have it run on a balance machine at a tire shop. It should show up. I had four Michilins on a Jeep wagoneer have tread separations all at once - four tires. It was a major consternation for me and the dealer. Got new tires.... went to Goodyear - no more tread separations. This happened in Alaska 15 years ago, so no telling what the problem was. Old tire rubber, maybe. Who knows. Good luck.
