Symptom of worn outer CV joints - clicking noise, starting when the 
steering wheel is turned, as the wear progresses, clicking when 
loading/unloading the joint as well.

Symptom of bad inner CV joints (quattro : propellor shaft CV joints as 
well) - shaking on acceleration.

Remember the inner CV joints are designed to allow lateral movement of 
the axle shaft, the outers are not, but are designed to run at greater 
angles of deflection.  Because of this, they show different wear 
symptoms.  I have never seen worn inner CV joints show any other 
symptoms (while driving) than shaking (or shuttering) on acceleration.

BTW, most (all that I have seen) CV joints come with instructions that 
insist only CV joint grease be used.  CV joint grease is specifically 
formulated for its task.  It has a high lead contact to deal with the 
high pressures/low movement the bearings encounter.  I have not had as 
much durability testing experience of CV joints as the manufacturers, 
so I cannot dispute their recommendations. :)
