I replaced my power steering pump it was a Cardon by Napa it went out Four times. I got a new pump from Auto Zone it went out. I replaced both high pressure lines an put a filter inline. My question is; could the issue be caused by the filter or my rack losing pressure while operating thus causing my pump to go out? Five garages cannot figure this out!

This would be hard for us to figure out as well when you say you have had five pumps go out what exactly happens? Does it get harder to steer all at once or over a period of time. Is the correct fluid being used? Does it start to leak? Have all lines been checked for blockage? I doubt it is the filter as it happened before you installed it. When pump goes out has it lost pressure? Has all air been bled from system after pump replaced.

Pump was bled exact fluid level, no leaks, steering goes just like that which has us all baffled. New pump will work great for a week to ten days after that same exact issue (power steering pump). We are thinking its the switch power steering or the rack itself no idea at this point!

I doubt very much the switch is the problem. It must be the rack taking to much to turn it in either direction.

We now have everything new including the power steering switch in testing. It is no issues works great. We here are all guessing the only thing left is rack we are on hook for this one we got to be right this time.

Just for giggles, if you can take an inch pound torque wrench and test new to old on steering column shaft see if there is a difference on a couple of turns in either direction.

We replaced that on the second pump I am ready to call a priest into help. We tested it again it has a moan again. I have a new rack on the way stay tuned. We also ran computer to sensor every thing is spot on. The truck came in for an alignment an steering pump moan. Pump was shot fluid was beyond dirty with gold small flakes in the res. Flushed six times to clean system. I will talk with you tomorrow. Thank you!

The small gold flakes should have been a tip off that something else was wrong besides pump. On a lot of these the valves make the noise and it is from using incorrect fluid.

Got new rack in and it is gone. The old rack was not leaking everything seamed good we did a leak test ourselves an found that is what took all the pumps out. HMAC300 our hats are off to you. Thank you, PRH-Inc.

More than likely the seals were shot inside and was causing grinding making the metal flakes. You guys kind of eliminated everything to fix it.
