Steering U-Joint - DIY ?

[Lacostas]

Hey there,

Im having some issues with my Steering wheel, actually you can see and hear the noise it makes ( https://www.dropbox.com/s/kdait84zeip5h6r/video-1514329346.mp4?dl=0 ) . I checked the outer tie rods on both sides and all seemed good. Also no leaks or whatsoever. The sound and feel, is like a bolt has come loose or something. How can i check the upper U-JOINT of the steering ? I tried to check under the drivers dash but couldnt find it.

Thanks
