@Hooy - can you please better describe the noise you were hearing from the bad steering pump?
@berserkerx - no, i never hold the steering wheel while at full lock. I just non-intentionally hit full lock while parking the car (not much space for maneuver) and that's when i hear the squeal. I back off the wheel immediately.
The thing is that the noise had completely disappeared for a few months after the dealer replaced the crank vibration damper. Now i don't know if that is the actual problem (and the new one has gone bad also) or it's a combination of that and steering pump/other.
