I heard some clicking in 3rd gear from the front axle last ride.

Today took it for a quick ride. Now its a constant click, quad turns to the clicking side. I had to force it to ride straight. Lots of vibrations and it looks a littler lower on the right side now.

Just want to know if this is cv axle or differential?

I have this mostly apart. When I turn the passenger wheel to far it clicks every time. Theres only a little tear in the boot. On the other side I dont hear noise but a boot is shot and theres a lot of fluid where the axle meets the differential.
