It is a quick replacement that only needs the clamps replaced if the hoses are in good shape.

As your system wears out there are only three issues to determine: rack, pump, line pressures. Only diagnostics will determine which is the issue and hence source of the problem. Any competent shop can determine this will a pressure gauge.
Helpful?
Stephen, is there no way to clean the filter inside the reservoir? I'm not getting noises but the steering gets heavy in the first quarter turn....as if something is caught. If I quickly release and turn again it goes smooth I've sucked out the fluid from the reservoir once last week and it helped just a little for 2 days. The hoses are dry and nothing visible under the car.
