    OK, the 'O' ring stopped the leak. Now I have a Question; if I use break fluid instead of pwr steering fluid will this cause any issue? The steering seems ok at low speed, however any thing above 40mph and the truck seems to "follow" the last turn of the steering wheel. I have to constantly correct the trucks heading. (If I let go of steering it doesn't straighten out).

    I wouldn't use it. They aren't compatible at all. Power steering fluid is petroleum, brake fluid is glycol. They don't lubricate the same, and brake fluid can be caustic to power steering seals. You can use transmission fluid in power steering systems.

    Understood. Will now proceed to drain and service pwr steering pump. Thanks for the feedback!
