Power Steering Pump Whining

f00g00 · 03-10-2008, 04:10 AM

I just changed mine, got a good one from the junkyard because mine sounded like Chewbacca at his whiniest. Mine was a constant whine due to bearings being worn.
Yours could possibly be air scince your constanly adding fluid. Get the leak fixed first, bleed the Hyd system and see if the problem goes away. It wouldn't be smart to change the pump and not fix the leak too.

It's got a vaccum leak and you have air inside the p-stump it self.
Much like your coolant system.

Give it a burp and the noise will go away.

Mmmm... Ok, Makes sense, How would I go about burping it? I know I will have to fix the leak before hand but in the mean time, please enlighten me. Thanks.

How I go about it...., and I'm sure there are variations of technique.

I pull the cap and watch for bubbles. I let it run. I crank the wheel back and forth from 1 polarity to the other and work it till I don't see bubbles.

Even with this..., my pump whines like a wookie upon initial start up.
But after that it doesn't do it again.

I attribute this to an advanced reman oem p-stump.

If you top off the fluids. Poor it slowly with no brakes to prevent air even going inside the system.

Hope this helps.

Yea, I have done that a few times before, but I only did it once or twice though. I didn't think to do it until no bubbles, as I never really look for bubbles, but I will now. Thanks.

Most people do it till the whinning stops.

If you have someone turn the wheel you'll see bubbles like an aquarium at first.
