pwr steering pump?
So I have replaced my pump 5 times now.... they usually last 5-9 months lol.... Now this one has taken a crap and will only work in a higher rpm range. is there an aftermarket one? the oem replacement is a piece and im tired of replacing it.... I am also getting a huge pressure seal whenever I open my resevoir? any ideas?
Thanks to those who helped me with my brakes it took about 10 mins to put the rotor and pads on.

5 to 9 months isnt a long time for a pump before it dies. Im thinking you have something else going on thats taking the pump out. Having the system bleed off when you open the can....id almost wonder if you have a restriction or clog in the lines causing the issue over time for the pump. Just something to think about.

nope i keep my wheels straight until i turn... and i also purged the system and replaced all the lines last time i fixed the pump problem...... my rack and pinon is good too.... i have run out of ideas

Are you running oversized tires? Something must be binding or the lines are clog if you gone through 5 pumps. I have PSC Extreme Duty on my Jeep. I don't know if they make a pump for the Ram if they do its a great product. Also I would check to make sure something is not out aligned on one of the pulleys

yeah i know right thats what i thought maybe a clogged system or maybe something else.... but its not i purged the whole system with air... replaced all the hoses.... replaced the pump (( this was all last time))... and im running stock tires and rims.... it makes no fricken sense along with all that thes stupid intertmitten wiper settings keep going poltergeist on me lol but i hear thats a major problem

It sounds like you are building up to much pressure, I found this online but it only goes up to the 5.9L systems so I dont know if it will help any but it may be worth a quick read through to see if you can pull any info off of it.
PUMP FLOW RATE AND PRESSURE
The following procedure is used to test the operation of the power steering system on the vehicle. This test will provide the flow rate of the power steering pump along with the maximum relief pressure. Perform test any time a power steering system problem is present. This test will determine if the power steering pump or power steering gear is not functioning properly. The following pressure and flow test is performed using Power Steering Analyzer Tool kit 6815 Pressure Test Gauge and Adapter Kit 6893.
POWER STEERING ANALYZER INSTALLATION
WITHOUT HYDRAULIC BOOSTER
Remove the high pressure hose from the power steering pump.
Connect Tube 6844 into the pump hose fitting.
Connect pressure gauge hose from the Power Steering Analyzer to Tube 6844.
Connect Adapter 6826 to Power Steering Analyzer test valve end.
Connect the power steering hose from the steering gear to Adapter 6826.
WITH HYDRAULIC BOOSTER
Remove high pressure hose which goes to the steering gear from the tube coming out of the booster.
Connect Adapter 6826 to the Power Steering Analyzer pressure gauge hose.
Connect pressure gauge hose to the tube coming out of the booster.
Connect Tube 6844 to the steering gear hose and Power Steering Analyzer test valve end.
FLOW AND PRESSURE TEST
Check belt condition and tension.
Open the test valve completely.
Start engine and let idle long enough to circulate power steering fluid through flow/pressure test gauge and to get air out of the fluid. Then shut off engine.
Check fluid level, add fluid as necessary. Start engine again and let idle.
Gauge should read below 1034 kPa (150 psi), if above, inspect the hoses for restrictions and repair as necessary. The initial pressure reading should be in the range of 345-552 kPa (50-80 psi)
Increase the engine speed to 1500 RPM and read the flow meter. If the flow rate (GPM) is below specification (Refer to pump specification chart for GPM) the pump should be replaced
CAUTION: The following test procedure involves testing maximum pump pressure output and flow control valve operation. Do not leave valve closed for more than three seconds as the pump could be damaged.
Close valve fully three times and record highest pressure indicated each time. All three readings must be above specifications and within 345 kPa (50 psi) of each other.
Pressures above specifications but not within 345 kPa (50 psi) of each other, replace pump.
Pressures within 345 kPa (50 psi) of each other but below specifications, replace pump.
Open the test valve and turn the steering wheel to the extreme left and right positions three times against the stops. Record the highest pressure reading at each position. Compare the readings to the pump specifications chart. If pressures readings are not within 50 psi of each other, the gear is leaking internally and must be repaired
CAUTION: Do not force the pump to operate against the stops for more than 2 to 3 seconds at a time because, pump damage will result.
PUMP SPECIFICATION
ENGINE RELIEF PRESSURE (P.S.I.) FLOW (G.P.M.) at 1500 RPM
3.9L 1400 to 1500 2.7 to 3.1
5.2L 1400 to 1500 2.7 to 3.1
5.9L 1400 to 1500 2.7 to 3.1
8.0L 1400 to 1500 2.7 to 3.1
5.9L Diesel 1450 to 1550 3.1 to 3.5
All With Hydraulic Booster 1450 to 1550 3.1 to 3.5
NOTE: After preforming test and removing Power Steering Analyzer, check power steering fluid level.
This is about the only way you can test it if the wrong fluid has been added it may have damaged the pump and valve.

haha well ive already done this procedure.... but it was a good idea... when i say i have done everything i truely mean everything..... I worked on pneumatics and hydraulics in the navy so i know all about pressure tests..... My problem lies within the pump... I just find it hard to believe ive gotten 5 bad ones in a row.... like i said before i replaced all the lines and the pump last time and purged the system.... I added the new fluid which i added the fluid it called for.... I am at a loss... im about to rip the whole system out and just use muscle to turn the truck.... which I really dont want to do....
