Power Steering Cable Cracked (Repair Question)

Hi everyone

Im new to the forum. I tried to post in the proper section. If Im wrong please let me know and I will move this thread.

Last week I bought a 2002 trailblazer LT 4.2 inline 6 at 164K. I took it to a mechanic and found out that it needed a few things. I was aware of the exhaust leak and expected other issues as I only paid $4000. Which is fine with me, but I am looking for some advice on how to go about fixing them.

My question is regarding the power steering repair. The other repairs I will inquire about later, but as of right now the power steering is priority.

I have attached a picture of the power steering hose that cracked on me while transporting the vehicle from the city of purchase to where I live. Approximately 500 miles into travel it cracked on me. Please correct me if Im wrong but to my knowledge this line is the high pressure line. If you look at the picture http://www.dotphoto.com/Go.asp?l=nic...&IID=263360899 the line that I need to replace has duct tape on it. Please don't laugh, I only did that to get home, so that I could keep the system lubricated to hopefully save the pump (I still had 100 miles to travel to get home). Also judging by the two hose clamps as you can see in the picture, it looks like the previous owner may have repaired this himself at some point. Again correct me if Im wrong but I don't think that would be something that would come from factory. Nevertheless, this is where Im at currently. I priced out the part that I believe I need. Pricing is as follows.


High Pressure Power steering Cable (part only) $199.09

Chevy Dealership $908.00 (including labor)

I am mechanically inclined and would like to do the job myself. At the same time, I am a tradesman and understand that some things are better off left to the professionals. What is your opinion on if this is a DIY project. I am confident with the replacement portion of this job. I am more concerned with the bleeding of the system and then refilling the fluid. I don't want air in the lines or any other problems. Any information regarding this repair would be much appreciated. I am very happy I am part of this forum and look forward to contributing information in the future, as I will be doing much of the work listed above (possibly all) myself, if, and I will share all of my tips and experience with everyone in the hopes that I can give back to our community.

You can replace the line yourself. Not a difficult job but it is time consuming as the hose runs all around the engine compartment, to the PS cooler, and over the drivers side inner wheel well (if you're replacing both the high pressure and low pressure lines).
As for bleeding, what I do is get the front tires off the ground, fill the PS reservoir, start the engine and turn the steering wheel all the way left and right a few times. You may have to fill it 2 or three times and it will be noisy.
When the fluid level stabilizes, add until the level is just above the 'add' mark, take it for a ride and check again, add as necessary.
