I recently replaced my original rack & pinion due to the same issues as yours. I bought a remanufactured one from summitracing.com for $193 plus core charge of $75.00(refundable with return of old rack). The unit came freshly painted with new seals, o-rings, inner tie rods, boots and warranty. I also replaced the power steering pressure line(autozone $75) and return hose as recommended.

or you can get a rebuild kit for around $70 from autozone.
