Default Power steering pump issue

I have a 05 2.5 N/A Outback and am having some issues with the P/S.

I have a squealing belt o, but I know that the belt is getting on in age and will be replace very soon, but my main issue is the steering feels notched (best way I can describe it) when its cold or a low speeds like a U turn.
Is this just related to the belt slipping? it doesn't always make a noise when it feels notchy.
Is the P/S pump on the way out or does it just need a flush?
Any help would be appreciated

Short term, either tighten the belt a bit more or use some "belt dressing" (although I usually hate that stuff).
See if the notchiness goes away.
If yes, great.
If not, maybe have additional bits ready when you replace the belt.

How old is your PS fluid?
Is your PS fluid low?
Do you have a leak in the PS system?

Sounds like you may have air in the system. I know exactly what you mean by the "notchy" feeling.

If it's a "on-off" tightness when you turn the wheel, it could be a binding steering coupler. If so the best fix is to replace it, but it may be possible to free it up with a liberal application of PB-Blaster.

So I got myself a new belt over the weekend, helped the squealing but not the notchieness, but had a friend over who has bleed power steering before and once he did that its all good.
I think it was original fluid with about 195k kms on it.
