I had the exact same problem. I removed the steering gear (no small task) and had it rebuilt by an auto parts place in Burbank, CA for $115. And I'm sure that it would have worked perfectly, if I hadn't put in the wrong fluid. Every expert I asked gave me a different answer (including Chrysler dealership parts managers).
Do NOT use ATF+3 or +4 (Automatic Transmission Fluid).
Do NOT use Dextron/Mercon, or anything with Teflon in it.
Do NOT use just any common market Power Steering Fluid.
Only USE Chrysler's MOPAR Power Steering Fluid.
It's like $15 a quart, at any Chrysler dealership's parts department.
Also, there is is distinct advantage to having your original rack rebuilt vs. Purchasing a new (or newly rebuilt) part " first, the $$$ savings, and second, it fits back in with no surprises.
