Default Knocking Noise?

I have a 2003 Impreza Outback Sport. Whenever I'm at a pretty low speed and i make a sharp turn, (U-Turn, pulling into a parking space, or reversing out), a knocking noise comes from the front end of my car. I've read in other places that it could be the center differential, but i'm really hoping it isn't. Does anyone have any possible ideas or suggestions?

Could be power steering issue? I had same tick-tick-tick sound whenever I make U-turn and the steering wheel to the max.

Does it only happen when turning in a certain direction? i.e. left, right or both. I would check the integrity of your suspension bushings specifically the control arm bushing.

It usually happens at its max turning capabilities or close to them. I don't really know what it could be.

I'm pretty sure It's for both directions. I'll check today when am out of school. Thanks for your suggestion, I will let you know what is going on.

I had that problem in my 02 Legacy but only when I made hard lefts. It had to do with my alignment.

Knocking at high steering angle sounds more like a CV joint (axle) issue. You could have a friend outside the car watching the front wheel when it happens. Most CV joints have 3 segments, so you would have 3 knocks per revolution of the wheel. You can watch the valve stem.
This would more likely happen in one direction not the other.
Diff would more likely happen in either direction.
Wheel bearing would likely also happen more in one direction than the other and more than 3 knocks per wheel revolution.

How many miles on the car?
Were axles/half shafts ever replaced?
