I changed my driveshaft.
And I made sure that I got everything good and tight.
And now when I get up to 55-60 mph it starts to vibrate.
What can be causing that to happen?

Welcome to 2CarPros. The description sounds like a stiff U-Joint or the shaft isn't balanced properly. Is this a new or used driveshaft? What was the reason for the replacement?
