When the cv are on the rear the normal turn in a circle is not a very
reliable check. This works great for front cv though. The rear cv is more
flexed in up and down motion.
I have found that severely pitted rear cv will give a vibration at certain
speeds. However I have seen rear bearings do the same.
The best way have found for isolating rear cv problems is to carefully
remove and clean to inspect the balls and race looking for pitting and
severe wear and then repack if okay. Sometimes all that is needed is a
repack.
