PS pump already gone?!

Been a long time since my last post (problem..).

About 1-2 years ago, I changed my PowerSteering pump because it was making noise and the issue was fixed.

For the last few days, for some reason, I find the steering way harder than before. I checked the PS Fluid (Dex3) and everything seems ok. No leaks (beside the know one on the reservoir). When I turn my steering to the far left or right, I hear a sound that I had before on the last PS pump so I thought it's normal. What can it be beside the PS pump? Tomorrow I'll remove the air filter box and will check for the belt or the pulley, but if the pulley is seized or something like that, I'll have to buy a new PS pump right? IRC, the pulley was attached on the pump when I bought it.

Any input and advices are appreciated.

Dex 3 is ATF?

Have you been doing regular flushes to keep your fluid fresh?
Did you change out the reservoir w/filter when you last changed the pump?
What is the condition of your fluid currently?

If your pulley is seized, your car would have no elec, or engine cooling.

Did you flush out the system when your old pump failed? Leave stuff in there and you'll ruin the new pump.

Only other component in this system that means anything is your rack.

Since my PS pump replacement, I didn't do any flushes. The level is good and the colour as well. Yes I did a full flush when I changed the pump but didn't change the reservoir.

I didn't have the time to check this out this week-end because of the rain :/ I think I'll go to a garage Tuesday and I'll get this checked out.

Can you share what you found, what you repaired and did it solve the problem. I think a bad reservoir (clogged filter) would wear out a new pump very fast. In most cases, replacing the reservoir instead of the pump would solve this kind of problem - and economical fix.

why not just tell us your problem if you have one.
Can also learn from DIY's and on youtube.

My problem was fixed by replacing the reservoir. I asked because in this case, OP replaced the pump and the problem came back soon - reservoir was not replaced. I am curious to know if the problem got fixed by replacing the reservoir eventually. This is good info because the pump is suspected when the reservoir may be all clogged up.
