check for external leaks first.
then check fluid levels. replenish as necessary.
Then.... u can peer into the steering reservoir hole and check for the oil churning in the reservoir. If u don't see any oil movement, then steering pump is failing or has failed.
***warm engine at idle - what is your RPM?
***while at idle and you turn steering wheel - does RPM go up , remain steady, or go down?
if u can rev the engine(or get an assistant) to rev ur rngine at idle while looking into the reservoir.... is there a marked difference in the oil movement?
if little or no discernable difference - it's a confirmation that pump is out.
if movement of oil is markedly increased - then the problem might be line blockage or the rack and pinion assembly is the part at fault.
How is quality of oil? if dark brown to black, I recommend a thorough flush first then re-test. Check for metal in power steering oil...
