I have a leak from the hose below. You'll see a clamp on the hose where the hole/leak is. I'm not sure what this part is but it looks like it turns into a metal tube and goes towards the engine . I am hoping that I only need to replace the hose.

Does anyone know anything about this?? Best way to fix it etc? The clamp helped at first (if we kept from turning the steering wheel all the way) but now we need to add a bottle every day.

Any thoughta on the part (so i know what to order and research etc?). The cost, the ease of installation, etc ? Ive never dealt with this before.

Thank you for the help!

Just order up some new lines and swap them out.

Yup. As @swathdiver says, common problem and an easy fix. That's the power steering pressure hose that's leaking. I literally just replaced that on my 2007 last week. Took me maybe 20 minutes, all in. You don't need to replace the return hose because it's unpressurized and unlikely to be leaking anyway.

The only tricky part is getting the new hose fitting threaded into the back of the power steering pump by feel, so that ate up 10 minutes of the job or I'd have been done even faster. 5/8" (18mm) combination wrench for the pump fitting and an 8mm socket for the steering rack end. I found it easiest to work from below for removal and from the top to get that fitting on the back of the pump seated right and a few threads started before tightening it down. The hose will come with a new o-ring for the power steering pump end, and new insert seals for the rack end. Don't bother with the seals for the rack end because they're a pain to get out and mine were still pliable. But definitely replace the o-ring on the pump end because it's easy.

Also, most major auto parts stores will have the exact part in stock if you're in a hurry.

Do you think there is a difference between getting a 20-30 dollar one vs a 50-60? Aside from $30 ;)

For that particular part, no. Edelman is one of the brands Rock Auto sells though, so I'd be inclined to get that one for a little peace of mind. For 90% of the parts on these trucks though, it's OEM or nothing. I put new aftermarket (Moog) tie rod ends on my 2007 three years ago, and one of them already has a torn boot and is getting loose.

Might want to consider a new pump also, since you have been leaking since march!

I am LOST and frustrated. I have other stuff going on too, so my brain is not cooperating. I CANNOT find the nuts to unscrew and swap the line. I THINK I have the one going into the engine or wherever it's going. But the one that is near the other hose (they are both connected to it).... It just feels round . my eyes suck so I can't really see. But there does not seem to be a nut there.

Alap, hopefully that's the right part. Amazon "SAYS" it fits....

It SHOULD be as simple as unscrewing one end, then the other. Put new o-rings on new hose. Install. Put fluid in. Bleed by turning wheel. No?

It should be the upper, single line in that first Pic, with the mounting bolt next to it.

As for the one on the back of the pump, that's a tube nut that's mounted at the end of the tube.

Look at the ends on the new replacement hose you got and you'll see how it's connected

Here's a dumb question...
I have a 16mm. But not an 8mm (or 5/16) ..... Can I get away with using an adjustable wrench on it?

Okay, I got my pressure side hose out. But the new part I have (that "fits " according to Amazon) has threaded ends on BOTH sides.

Does anyone have a part number or links to the proper high pressure hose (2007 Denali)

I tried to put the hoses back (what a PAIN - no room to maneuver a wrench or the tubes ). And I have the one on behind the power steering pump. But my fiance , naturally, called me as I took the other side out (with the coupled tubes that I had to remove the bolt to take it off) she had me do something in the house and when I walked back I totally lost where I pulled it out from. I was feeling around for 2 holes but don't feel anything. What a nightmare this has been - for a supposed easy job.

I am sorry, I am not following anything any more because the verbage is changing. And I'm not experienced enough to know what you're referring to. I know I need the high pressure power steering hose.

The 1st post says trans cooler line 1 abd trans cooler line 2

The link posts refer to it as an inlet and outlet .
