A c/v joint will cause a ticking vibration. The most common cause of c/v joint failure is a torn c/v boot - look for a torn c/v boot.
An air pump will groan most of the time, regardless of the steering position.
A failing powersteering pump will groan, and squeel. Remove the powersteering pump fluid reservoir cap ( with the engine running) and slowly turn the wheel from side to side. Look (with a flashlight) to see if there are any bubbles in the fluid inside of the reservoir. If there are-it is a powersteering pump.
Since we are playing 'guess that groan' my guess is POWERSTEERING PUMP. Keep me posted and tell me if I win.
