2005 acura mdx power steering pressure hose replacement cost

I replaced my power steering high pressure line with the mechanic. However, immediately upon starting the car there is a loud whine without turning the wheel or anything. And I mean it is loud. When it is really cold it is the worst. We have had a couple 60-low 70 degree days and the sound is softer on start up but still there.

Before replacing the line, I saw the system leaking power steering fluid on the high pressure hose. Even after it was replaced I didnt see any bubbles in the reservoir. However, several weeks later I am seeing bubbles. Could this be from a rack and pinion? Does the rack cause that much noise when not being steered? The mechanic mentioned that a seal is leaking from the rack (not much and didnt have to be replaced.)Should I replace the O ring? Does BlueDevil Power Steering Stop Leak work with the rack and pinion for helping the seals?

Any help would be appreciated! Thanks.

If you can't determine where the leak is coming from, I would try the O rings. Cheap and easy. Is it possible it is the pump itself? Good luck.

Phins2rt and LeftOverParts are right - chances are very good that the problem is the o-ring on the suction line (not the high pressure line - a bad seal there will just leak). I should add that it's generally a good idea to cycle the steering wheel lock to lock a few times after replacing the high-pressure line (or other major component in the system) to force out any air in the system. It's always better to do this with the wheels off or the tires off the ground (since it won't stress the steering components that way), but if you can do it while rolling along in a parking lot (dirt, if possible), it's just as good (as long as you don't crash into something in the process, of course).

Just out of curiosity, what did the mech charge you to swap out the high pressure hose? It's one of those jobs that can be frustrating to do in your driveway, requiring some tools not everyone has in their toolbox.

Thanks everyone. The mechanic charged me $550. The part was $200...he mentioned my seals we're leaking in the rack, but shouldn't be a problem immediately. I read that the blue devil product could help with the seals. $1500 for a new rack is a lot of $$.

I will try the o ring. However, does the rack cause all that noise? It sounds like when you have no power steering or a low amount of ps when starting the car.

Is the PS Line OE? A Honda tech once told me that the OE Honda PS Lines have a silencer inside that some aftermarket lines do not and cause a severe whining noise.

The noise you hear is the pump eating the bubbles in the PS fluid. Swapping the O-ring is one of the easiest jobs on our MDXs - it's just a few bucks, and five minutes with a closed-end 10mm wrench (preferably one with a little angle offset to facilitate reaching the bolt holding on the hose attachment through the pump's pulley holes).

I'd be curious to hear about any "silencer" in the high pressure hose. I suppose it's possible that Honda uses a thicker, more sound-absorbing hose than aftermarket manufacturers. But the hose itself doesn't "make noise" - only the pump can do that, and I have doubts about how much of that noise the HP line "transmits" through the fluid.

Mine just blew PS fluid all over the driveway. Took it to Honda this morning, pump ($400) and line ($900) bad and need to be replaced.

OP, curious where you live. The OEM hose is $120 online and the rack $900.

Pretty sure "ITGuy" is quoting parts plus labor. Sounds kind of like Honda pricing (with the big up-charge being the labor for the fairly fiddly job of swapping out a bad high pressure line - at least I can kind of sympathize with them, having done it myself in a relative's wet driveway). ;-)

That said, it should be possible to get better prices from an independent shop, and neither of those jobs are pretty straightforward - if they put the new parts in and they work and don't leak, it's a good job.

I'd at least want to know that the high pressure line IS leaking (mine sure was!) before committing to replace it. If it's not leaking, it should be perfectly fine.

Also, the majority of power steering pump diagnoses seem to actually be failures in the $2 O-ring on the suction side. If there are air bubbles churning through the fluid (and it's at the right height, of course) then it's very likely that the REAL problem is a bad O-ring (a 10 minute job to fix). Happens to nearly all MDXs eventually it seems. Did to mine, and causes all sorts of odd noises out of the pump. I'd certainly check that out before coughing up big bucks for a new pump. Even then, rockauto.com has remanufactured pumps for mid-$60's to $110 or so, and the HP line for $70 to $125 (I think I went with a $90 Gates hose on mine - worked well, though the fitting for the pressure sensor isn't exactly like the original and resulted in a tight cable - not a big deal, JFYI).
