Although snapshots were taken at extreme angles, the cv joints appear to be intact. The gap between xmission and shaft may be a clue or nothing. In general, cv joints are secured on both ends The metal boot shown is where three ball bearings are allowed to slide in and out of the cover fitted snugly over them. The ball bearings are mounted to one side of the cvj with the metal cover mounted to a splined shaft that slides into the xmission. A circlip holds the xmission side of the cvj. The wheel hub side of the cvj has splines to match the cvj. The wheel hub side allows side travel of the cvj, not the xmission side. The majority of cvj angular travel doesn't allow the cvj to fall out unless the wheel hub is torn off in an accident. A slide hammer type of tool is needed to yank the xmission side of the cvj to overcome the circlip locking the shaft to the xmission.

There may be one more test to verify both CVJs are intact; shifting into drive with engine idling and in forward or reverse, checking both driveshafts aren't turning with brakes applied. If any one drive shaft turns in place, that cvj is broken. Two people should be performing this to ensure one has the brakes applied with xmission in reverse or forward while the other one looks at both driveshafts from a safe viewpoint. If you are assured both CVJs are intact then skip this step and move on to other troubleshooting.
