If you don't have lots of oil on your driveway from some major leak.
There is some treatment that you can try that sometimes will stop a minor leak
by swelling up old leaky seals. They have it at all the parts stores. It's worth a try, get a turkey baster and remove as much of the old stuff first and try the additive. Maybe you'll get lucky.

Well, you need to get the car up on a rack to check all the components of the P/S system. If it's the pump or high pressure hoses leaking it's not too expensive. If it's from the steering rack it is expensive. I just did the rack on my 1993 with 220k miles. It was leaking from the tie rod boots, front right, behind the wheel. Not a DIY job. The local mechanic did it for $950. (parts, labor and wheel alignment). When you top up the P/S pump be sure to use ATF (transmission fluid). It's worth it if you are going to keep the car. A new rack really improved steering and handling. If your mechanic participates in Costco's repair program they give a 15% discount. Mine did and that brought the bill down to $800 plus tax.
