Have an issue with my power steering getting hard after the car warm up. In the morning, when cold it feels loose and easy to turn, but after a while it gets hard to turn when the car is parked. While I drive is ok, but trying to park the car is a bear.
I have replace both O' rings replace the fluid, bleed the system but no help. It looks it may be the pump gone or should I look for something else ??

Note; there is no noise coming from the PS, and no foam when looking in the reservoir...

For starters, when was the last time you changed your serpentine belt? And have you ever changed its tensioner?

As mentioned check the condition of your serpentine belt but an issue there would affect other belt driven components.

Hum ha.. ho.. well I guess I never did... would that affect it.??
I inspect it when I actually removed the pump to replace the o' ring on the high pressure side and it looked pretty good..( The serpenrine belt)
I would think it would squeak or would give me other indication.. I run the A/C all the time and that also has no issue..

Edit: ¿Por qué double post?

Double Edit: Never mind.



I still want to say serpentine belt and/or its tensioner, but it may also be the PS pump itself.

If you're going to fire the parts cannon, may as well start with the cheapest ordnance.

I'm leaning towards worn out pump. If the tensioner or belt were failing, you would be having alternator and AC troubles too.

I will be replacing the serpentine belt anyway at 186K miles I think she done her part. As far as the pump.. New AFT market ? New OEM? Rebuilt ? I have seen some on Amazon for 60 bucks but I don't trust the chinese crap on amazon . is only a waste of time

The decision is yours. The power steering pump is so easy to change out, I'd probably just get a rebuilt one with a lifetime warranty from a local parts store.

Could possibly be your PSF reservoir? There is a filtration screen in the bottom of it that will get clogged with PSF hose material over time and there is no bypass if it gets clogged up and will restrict PSF flow and add strain on your PSF pump. You can clean it or just buy a new one for like $20. May not be the solution to your problem but, it's cheap/easy and eliminate a possible culprit.
