Power Steering Issue?

Hello 2nd Gen Tacoma owners! Anyone ever had an issue where the power steering sounds rough, but the fluid levels are normal? It is gradually getting worse, and concerned if I don't look into this soon, it will damage the pump. Any suggestions would be very much appreciated!

 

My power steering started making sounds on me a month or so ago, noticed fluid level was down maybe 1/2 pint at most. I added fluid and I'm waiting to see if it's as leak or pump seal issue etc. 13 TRD sport with 175k.

 

Thanks for the response! My power steering fluid level is normal. That is why I am concerned. No leak here however.

 

Oh I just saw online that it could be trapped air bubbles in the power steering fluid, and a flush is recommend. I will try that and post the results here.
