U joints wear as does the slip yoke. A good driveline shop can give it a clean bill of health. There is the possibility that it's something else like a bent wheel. Driveline vibes are very high frequency. They make coins in the console dance and your keys buzz like an electric razor. Things originating from a wheel (the wheel itself or a tire) are about 1/4 the frequency. I have had poor luck with after market U joints. They don't fit well and the trunion walks back and forth in the bearing caps. Ultimately, after almost 300,000 miles I had to replace the entire thing. I had a driveline shop make one out of Spicer parts so it would be easy to get replacement stuff as I needed it.
