I have an 05 trailblazer 6cyl as my daily. Last Monday I developed a nasty power steering leak. I got under it and there's two lines coming out of what looks like the bottom of the steering column. They are right over top each other and held in with a plate and 6mm bolt. From there they run to the back side of the rack. I pulled them out and found two little o rings.

Now I'm not familiar with these vehicles at all. So I did a little looking and came across a recall. It stated that a hose could crack when braking and having the wheel turned all the way left or right. It also indicated that on some models the braking system would be effected as well. Right then and there I stopped. My ABS light came on that morning when I went to work. I really didn't think they'd be related but apparently there's a hydroboost system where the braking and steering are both involved.

So my question is has anyone else delt with this before? I don't see any cracks in the line but I didn't remove them from the rack. I was going to try and find new o rings but now I'm wondering if I need to replace the lines. They are hard lines not hoses.is this common and how do you guys go about fixing it?

 

Little update. I changed the o rings and no luck there. I had my wife turn the wheel with me under the car. When she turns it all the way right it sprays a steady stream of fluid straight up out of the top line. It doesn't leak at any other point while turning the wheel. The rack and column setup looks to be an expensive part to replace so I really don't want to start throwing parts at this thing.

 

Then perhaps you'll have to change the lines themselves.
