Power Steering HP Hose

KAHruzer · 07-01-08, 01:49 AM

Developed a leak in my high pressure hose of the power steering.

After looking, it appears there's more to changing this than a simple swap.
Anyone done this before? What's it take to get the bottom end of that hose out? Think it's done from the bottom and some cover plate must first be removed.

I'm going to have to go the yard to get one off salvage, so need to have all the tools and a plan prior. Priced it at the dealer....$279! just for the part.

Yikes, that's pricey. I've heard that high pressure hoses can be rebuilt as well. I can't quite visualize your problem, where is it leaking?

Here's a pic showing the leak. Thanks to whomever's photo that is I borrowed, it's not my engine.

It's coming out the seam of that metal-to-hose joint. From there, the thing is mostly aluminum tubing diving down to the steering box. Can't see the end from the top, so presume it must be disconnected from the bottom. I think the manual said there's a skid plate of some sort which has to be removed to access the steering box.

I've never heard of a hose like this being rebuilt. But, haven't checked into it.
Guess it could be all replaced with a straight run of alum tubing. Not sure why it's built the way it is. Pretty complex connector at that leak point which includes a flange to attach it to the engine block there.

There are also two mounting brackets with 10mm bolts on the lower part of the hose where it becomes a stiff metal line. They are pretty tough to get to and they are located behind the steering rack on the frame of the car along the bottom of the firewall.

Typical root cause of failure; any HP hose for that matter, where the rubber and pipe are crimpped together... YES it can be rebuild, with proper crimping tool of course and YES it can be replace with just aluminum line, but rubber is incorporated for flexibility.

KAHruzer, you're looking to replace this part... here's a diagram from the Rack&Pinion gear box, you'd be replacing line "A" : from pump... and here's a visual <= painted black... with gearbox cover on, held by four (vary in length) 10mm bolts.

You'd need to fanagle the line out from the top... goodluck!

Oh okay. I've seen that area when being under the car before. Glad someone who's dealt with it before chimed in.

The place that rebuilt a friend's fuel line for him was a hose and fitting supply store I believe.

Thanks for that, X. I presume one would go at it from the bottom rather than top side. But, appears I'll be down there anyway.

Appreciate the info.

I figured you had shots. That helps a LOT!
Thanks. The part photo certainly shows why it costs so much.

The hard part will be getting under a car which is set on hubs planted in sideways steel wheels, I suspect. Not sure that gives enough clearance to do what needs to be done. Anyone ever asked the yard to lift one? Guess I should bring my own jack and stands, huh?

I might check into this and see if it can be done locally.
Anyone know what pressures we're dealing with here?

The line pressure is ~1500 psi I believe.

The connection at the steering rack is easy. There is a metal cover that comes off then you need the correct size flare nut wrench. At the top the fitting to the pump is just a few small bolts and it has an o-ring seal. The two connections to the firewall sound nasty due to limited space. It wouldn't be too hard to unbolt and drop the rack and pinion down a bit to access the one that is supposed to be above the rack. You would have to disconnect the steering U joint from inside the car first.

I suspect you could get someone to make up a line for you more cheaply than buying a new one.

Appears the spaminator got your link. IAC, it doesn't work.

Ran into it in the manual. It's 1138-1280 psi. But, that probably means a 1500psi hose for safety margin.

I snapped a photo down the firewall from the top. All that's visible is the end of the hose where the sensor is located and its' connector (see below). It didn't appear to attach to anything there, but it goes out of sight as the firewall tapers to the back. Whatever it is, it's probably going to have be done from the bottom end.

The sensor was kind of a surprise to me. Wonder what it does exactly.

That ps leak is messing up my engine!! And power steering doesn't work at all well either, except for that short part of the drive when the reservoir is full. There's now also a 30" round spot in my driveway. Man, I hate that.

Stopped pouring fluid into it and it stays about a 1/4" below the LOW mark. Power steering is flaky, like a knotted rope.

What's the potential for damaging the pump or steering box here?

I got my PS line from AutoZone for around $95, if I recall. You may wish to check there, if you haven't already installed the one you have. Best of luck, it's nasty tight in there, but it's doable with some patience.

Not sure why, but I never even gave the parts stores a thought after seeing how complex the line was, including the sensor. Wouldn't have figured they'd come close. Still wouldn't if you hadn't mentioned it.

So, looked it up at AZ and there it was: AutoZone.com | Shopping | Parts | Product Detail - Power Steering Pressure Line Hose

And, only $69.99

I had also emailed several eBay Stores who posted other Legend power steering parts and asked if they had one around. Haven't gotten any replies yet. But, suspect they're not going to be much less than AZ, and used, when they do.

Thanks for that.
