I have 1999 F250 Super Duty 7.3 L truck that I am going to have to replace my 3rd power steering pump in less than 10,000 miles. Did not start until after I passed 200,00 miles, mechanic says this truck has problems like this all the time. But my question is why did it take so long for the problem to start? Any help with this issue and advise would greatly be appreciated.

Reason: wrong year of truck
Also if the pump put metal thru the power steering system it will eat the new pump. In the shop I work in had a dodge pickup that had several pumps go bad really fast. 3-4 weeks right after the other. We flushed the system out reallly well the last time to get all the old fluid out.
Good point to the above!! Was the entire system flushed after the first pump failure??? Most rebuilders require you to flush the system and install an inline magnafine type filter.
I don't know how the pump was installed but the mechanic did make sure all air was out of the line both times. But the last time it was replaced he did state if it fails again he would have flush the system, but I will ask him to put in the magnafine type filter. Can I get this filter at an O'Reily parts store? The pully has not been replaced just the pump, should the pully be replaced as well? thank you for your help and look forward to replys. I also have 95 F250 7.3L but no problems with the pump just this 1999.
The pulley is swapped over each time he replaces the filter. He is reusing it and should be careful on how he does it. He should have done a flush the first time not wait until multiple pumps fail!!
I just went through this on my 92 4.9, very frustating due to poorly remanufactured parts. Original lasted 18 yrs, 130000 miles, then leaked. Bought a reman which lasted two weeks, then again a reman which was the loudest pump I've ever heard and I returned it. The system was flushed with Type F atf each time and the pulley was removed and installed correctly each time. I went so far as to perform the tsb using a vaccum pump on the reservoir to ensure all air was removed. Finally bought a ford pump which functions correctly and is quiet. I wasted about a case of atf between all this crap. What an enormous waste of my time! Tony
Believe me, I learned my lesson on this project. Something which should be so simple, take less than an hour or two turned into a week of Bull$&** and $40 worth of atf. All I can hope now is my slave cylinder holds or I will drag the parts guy with me to pull the trans and do it again. Tony
Please make sure the mechanic flushes everything out before installing the new pump or it will need to be replaced too. I usually replace hoses as well. If there were metal particles in the oil, they can stick inside the old hoses. Those particles can break free from the hoses when the oil heats up.
