intermittent power steering pump My power steering pump on my silverado 2500 was getting weak. I thought it would be a fun learning experience to rebuild the pump because I built transmissions back when i was in tech school. Well it didnt turn out as well as I planned...
The building process wasnt that bad and I followed the directions to the tee. Now when I start the truck, i have absolutely no power steering or power brakes (hydroboost). If i rev the engine, everything will work fine, but it howls/grinds LOUD as if it was bone dry.
Now.. if I let the truck idle for about 5 minutes straight.. the pump barely makes any noise at all and works perfectly! I have no clue what is wrong with the pump. Ive flushed the power steering fluid and bled the system twice. Does anyone have any clue as to what went wrong?
