When shifting the transmission into gear and accelerating there is a knocking/ticking sound?

This noise can happen when the CV axles are worn out and with 300,000 on the car they need to be changed, to be sure, can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. Here is how to change the axles out so you can see what needs to be done. Check out the images (below). Please upload pictures or videos of the problem so we can see what's going on.
