I have a 2004 chevy trailblazer with 3rd row seating and i have a hose that is leaking power steering fluid from the power steering box. the hose goes from the power steering box to the rack opioion and i dont know what is causeing it to leak or what that hose even is called

Power Steering Box Dirty

I believe it is a power steering pump. My car does the same thing and the power steering fluid was low. We completely filled the power steering and a week later it was low again.

Here's a guide to replace the pump,is that where it's leaking or bis it the hoses.Here are the hoses,to replace,drain fluid and loosen both ends,it's a super tight fit.

Sounds like you've lost hydrolic pressure. Did you check the 2 hoses connecting to the power steering pump? I take it, you lost power steering fluid also right? If it was leaking badly, it was the high pressure line that blew, if not, it was the return line. You can have a hose made for you for pretty cheap to replace the hose.

You have to determine where the leak is occurring, at the pump, hoses or the rack and pinion unit.

As you brakes wear down your fluid level goes down with them. The pulsing is probably tires.

Nope. 3rd row was never offered with a trailblazer even the EXT modles.

Dealer, but did you check the Power steering fluid level??or any leaks. There are two hose that connect to the gear box from the power steering pump. if the pump is low on fluid you lose your power steering, if the hose has a leak or it blew and lost the power steering fluid then you lost your power steering again. 
Check the fluid level to the power steering pump and any leaks or broken hose to the gear box.
Keep me posted, be glad to help and good luck.

What the seal leaks do is soften the rubber, not the best long term solution. Try taking a wrench, the correct size, and snug down all the fittings, not to tight. If it is coming from, as you described, down through the boot it could be a seal. Wipe down the unit well and watch as you have someone tune the wheel back and forth. The engine should be running to build up pressure, so be very careful not to get run over. Apply the emergency brake well and chock the tires.

2004 Chevy Trailblazer radio won't eject CD. Push the eject button and the thing just clicks and says "check CD" . Tried bulletin 04--8-44-020C (fuse removal and reinstall) didn't work. Any other suggestions before going to dealer?
