I have the truck listed above z71 with a 350 vortex engine, not the original engine. I was backing out of a tight spot and I heard a 'pop' from my front passenger side. Turning right immediately after, my steering started groaning. Next day found my steering fluid empty and on my driveway. Please if you can, tell me how I can pin point this leak/break, and how I might be able to fix it on my own. Limited funds as I was laid off very recently. :( When I went to try and pin point, I found everything saturated in steering fluid.

Steering 'groans' when the wheel is turned either way.

There are a couple ways to do this. The hard and clean way is to inspect all lines and connection points for cracking or holes. The easy and slightly messy way is to spray down the engine with a degrease spray and hose it off to clean it. Then fill the power steering and have someone turn it on to pressurize the system and then you look for where the fluid is coming out. Wear eye protection and keep you mouth closed, because if it is from the pump then it could be sprayed all around. You only need to run it for a second or two to find the area and then you can shut it off and will probably see the fluid still dripping from the location to pin point it.

Clearly this is not the most desirable process but it is quick and easy. Let me know if you have questions. Thanks

The groans are from the lack of fluid or the pump is going out. Let's start with finding the leak and go from there.

Pretty sure I found where the leak is coming from, the first picture is from underneath and I can follow the path the fluid takes and where it would drip from. On the second pic, when I pulled back the protective plastic tube I could see the power fluid rush to fill the gap between where the hose and steel meet when I manipulated the hose. Maybe that 'pop' sound was nothing related to this? Also, no groaning so I'm hoping I haven't damaged the pump. Or is where my leak coming from something that is attached to more = more money? Really bad timing so if at all possible I'd like to tackle this one myself.

Okay. No groaning is a good thing. Also, that could very well have been the noise. This system is under a lot of pressure especially when turning so if something lets go it can sound like a balloon popping.

All we can do is fix what we find broken and then retest. The frustration comes in (and it gets expensive) when we can't find anything and it still doesn't work. That is when people start guessing at parts or take it to a repair shop. Either way, it is more expensive.

I would just go ahead and repair what you found and retest it.

Thank you, I don't know if your able to identify from the pics which hose that one would be? Looking up hoses and there's intake/out take, return. Looking at online diagrams of Chevrolet Silverado without hydrolic boost, it looks like the inlet hose. Would I be correct to pursue that one?

Looks like that is the feed line that wraps around the pump. I included the diagram to try to determine this. I would follow the line down and see where it connects to the steering gear. If it is in the same location shown then that is the line.
