I have a 2007 dodge 2500 5.7 hemi truck. I am havingissues losing my power steer pumps. Original went out month ago. I put two endurance brand pumps refurbished in it. One didn't last 24hrs and the other three weeks. Then I put in a new oil cooler and gear box and new duralast pump. New pump went bad the next day. I replaced one of the pressure hoses as well. Now I bought an original used pumpto see if that made a difference and now it's starting to whine two days later. Nobody can figure out why I am going to through pumps. Any thoughts? I'm Losing my mind. Thanks.

 

How are you bleeding the air out of the system?

 

Just like the mechanic told me. Fill it up turn wheel back and forth till it stops going down. Start it up and work it back and forth till stops bubbling.

 

Pretty much correct. Do you have the front wheels off the ground?

I usually will jack up the front, fill the pump, start the engine, turn the wheels a bit, recheck fluid level...... then run the wheels from lock to lock a couple times. Let it sit for 30 minutes for the air that got whipped into the fluid to escape, top it off, and do it again. I keep doing that until I am not seeing any more air in the fluid. Sometimes, that can take a while......

 

That's how I did the last pump I put in. Jacked it up just the way you described. I have to pick up the other pressure line today to put on. Several people asked about the lines collapsing restricting flow. I replaced the line from gearbox to oil cooler.

 

Is there junk in the lines that is smoking the pump? That's about the only other thing I can think of.

 

I wouldn't think so. Going to replace the rubber return hose to reservoir as well. It's just a standard hose. After I do these two hoses, the entire system will be replaced.

 

Is there a cooler in there as well? (tow, or heavy duty package option, I think.) Flush that too.

 

Yes it does. I replaced it. I have a whole new complete system and oil. Just pulled the pressure
line off the power steering pump. Hopefully this is the problem. Looks little dry rotted. Put a new reseviour hose on it too. The pump was whining before I put this on and drove it around the neighborhood and it's not whining now. I have officially replaced every part in the steering system.

 

Does it work the way it is supposed to now?
