I've also performed a DIY power steering flush.
I was unable to take pictures of the process, but it was actually really easy...albeit messy:

TOOLS NEEDED:

-a pair of pliers

-2 quarts of your favorite ATF

- An empty 1 QT bottle / small container

OPTIONAL:
-4 feet of 3/8" hose & a hose mender


1.) Jack up the car so that the front wheels are off the ground & put the ignition into the "ON" position.
This will allow you to move the steering wheel lock to lock to pump the old fluid out of the return line.
(this method allows you to manually pump the old fluid out at your own pace, instead of the very high pressure that the PS pump would generate if the car was running)


2.) Remove the pass side air box & the wiper fluid filler tube.

3.) At this point, you should clearly see two hoses coming out of the PS reservoir.
The hose that leads straight to the PS pump is the high-pressure or "feed" line.
The hose that you'd need to disconnect is the one that's going down into the wheel well
(aka, return line)

4.) Use a turkey baster or any other suction tool to suck out the fluid from the top level of the reservoir. (otherwise it'll pour out as you attempt to disconnect the return line)

5.) Put something down under the reservoir to catch any spill-over & disconnect the return line form the reservoir.

6.) A this point, it'd help to have a short 3/8" hose to connect to the reservoir in place of the return line & plug or cap off the end (otherwise the new fluid that you pour in is going to leak out of there).

7.)Prepare an empty 1 QT bottle & point the return line that you've disconnected into it.
This bottle will catch the old fluid as it drains out.
-Optionally, you may purchase a length of 3/8" hose to attach to the return line using a 3/8" hose mender (this will make it easier to extend the return line out of the engine bay to make the draining process easier):

8.) At this point, refill the reservoir with fresh ATF up to the "cool max" line and have a helper start turning the steering wheel lock-to-lock. As they do that, you will see the old fluid coming out of the return line & into the empty bottle. Keep an eye on the fluid level and keep re-filling it as your helper turns the steering wheel, until you've gone through a full quart of ATF and your catch bottle is full. One quart should be enough to flush out your PS system. If you've been neglecting your fluids, it should be very easy for you to tell when you're fully flushed: the fluid coming out of the return line should be coming out clear RED instead of brown.

9.) You may now suck out/drain the top-level of the reservoir as to avoid any major spills as you disconnect your "capped" 3/8" hose from the reservoir.

10.) Disconnect your "capped" hose from the PS reservoir & re-attach the return line.

11.) Refill your reservoir with up to the "max cool" line & start you car. If you've attached everything correctly, you shouldn't see any leaks. Go for a little drive to warm up the fluid & check the PS fluid level. It should be at the "max hot" line. Add/remove some fluid if it's not.


CONGRATS!! You have now performed a power steering fluid flush, saving yourself $130!!
