Driveshaft dislocation

Long story short basicly I changed a pair of wishbones and when I put the car back on the floor there is no drive at all just a nasty driveshaft grinding noise.

Not sure how it actually went back together at all if the driveshaft isnt located but it did and quite easily

I'm pretty sure its come out at the CV end of things

In short how do I get it back in.

I should probably mention this is actually for a Mk4 platformed car but this forum is far more helpful that any other that I'm on and driveshafts all seem to be pretty much the same
