My power stearing has been groaning the past two weeks and has progressively gotten worse until i was parking yesterday and heard a pop and lost the power steering. There has been no sign at all of leaks and when i first noticed the noise I made sure to keep the fluid clean by replacing with Mobile1 ATF until it was a clean red color. Ive had the car since new it's an 04 coupe with 160,000 miles so i know that its the original pump. Would there be a leak or any other signs to point to failure? Not sure on what to do aside from just replace the pump. Thanks for you're help!
