1994 Buick Park Avenue possible u joint

I drive a 1994 park ave when I drove my car today there was a loud noise as if I had round over a tin can and I felt a bang as if a rock had hit under the car on the driver's side I felt it on the floor board my passenger side it's the u-joint I pulled over and turned off the car looked under car and hood i did not see anything. I started the car with no problem I drove back home and as I was driving the engine sound normal but there was a rattling on the driver side it was more of a ticking rattle and when I made a right tun into my drive way there was that sound again along with that bang. Can you help me out is this something I can fix myself? all I have to my name is 66 cent.
