I've had no issues with the Power steering in my TJ until yesterday.

When I turn the steering wheel to the right I get an audible hissing noise coming from the power steering. Turning the wheel to the left the steering is silent. steering feel is normal. And no comments regarding not turning the wheel to full lock cause I know that it is bad.

I checked the fluid and the level is fine but the fluid looks brown and had some solids formed on the dipstick.

How much fluid do I need for a flush and do I need to be thinking about a new ps pump?

Thanks guys
