My 1996 Impreza has a power steering pump leak that I have been nursing along by adding fluid maybe twice a month. Got car back from shop yesterday and drove today just 12 miles or so and pump was whining and moaning. Checked fluid and it is a different color, a lighter orange than the reddish fluid I put in. After doing some searching this could mean air is leaking into the system.
I just had the front ball joints done to pass inspection. Could work on the suspension adversely affect the power steering system , maybe a hose got lose or something?
