What's happening???

I went for a play about after work today and after trying forward/ reverse and hi/lo etc I got under it near the drivers front wheel and started playing with the front prop and there was quite a noise coming from that corner, so I put my ear to the tyre and sure enough there is some clunking going on in there.i went round the other wheels and did the same and there's definitely a lot more noise at the o/s/f. So I popped the wheel cap and hub cap off and it all looks fairly new n there, even the threads down the middle are clean bare metal like they were used not long before I got it, but I couldn't see to wiggle the prop and look at the drive flange at the same time so I'm guessing flange or cv. Il see if I can get a helper tomorrow and go from there
