    Anyone do a power steering flush yet? My PS fluid is starting to look pretty nasty and very dark. I guess if no one replies, I'll take a look at the FSM and pull the return hose to drain the system a little at a time, similar to the DIY ATF flush...

    I just did this, it was super easy. I have the 2.7L 4 cyl engine.

    Raise the front of the truck high enough so the tires are off the ground. Use jack stands to rest it on.

    Suck out or turkey baste as much of the PS fluid out of the reservoir as you can. Place an old towel or some old rags around the reservoir, because it's inevitable that you'll spill some. Disconnect the return line ( the upper one ) from the resorvoir, and plug off the nipple you pulled the line from. I just used a short piece of tubing with a bolt stuck in the end of it. Attach a 3 or 4 foot piece of clear transfer hose to the return line and drape it down to the ground through the engine housing. I used a plastic connector piece to connect the lines. Put the end of the clear hose in a container. I used a one gallon milk jug.

    Refill the reservoir with fresh fluid to the top. Get in the cab, turn the key to the on position and then turn the steering wheel all the way to the left very slowly. You will see the old fluid coming out through the clear hose down to the jug. Then slowly turn the wheel all the way to the right. Now go and put more fresh fluid in your reservoir, then go turn the wheel all the way the other way. Keep doing this back and forth with your steering wheel, BUT NEVER LET THE RESERVOIR RUN LOW ON FRESH FLUID. If you do, you'll let air into the system. The original fluid is amber colored, and since I used ATF fluid ( which is red of course ) it was easy to tell when the new fluid was coming out. Stop when you see new fluid. Now unhook the return line from the transfer line and re-attach it to the reservoir. Don't forget to put the clamp back in place. Clean up the area and top off the reservoir to the correct level, lower the truck and you're done. Check the level one more time after the first drive to be sure. I used about 1 and1/4 of a quart of ATF.

    Thanks for the write up...just did the change with my 2010 v6. Ended up using almost exactly one quart. FYI, I used a 2 liter bottle and it sits down in the engine bay perfectly so that you don't need to extend the return hose.

    Bump. I am also wondering which line is the return line so I can do this tomorrow. Also anyone replace the power steering filter? I didn't know it had one until I looked on rockauto. I figure thats a good thing to do when you flush it, no?

    I just take a small pump like on a soap dispenser... Pull out what you can get, refill it. repeat after driving a few days. I know you never get it all, but it is a sealed system. I do it every 20k. Amsoil is compatible. After 2 or 3 flushes I like to think I get 80% new. Never replaced a pump or had a leak with my last three trucks or my old mans! I do the brakes the same, except I open the rear bleeders, (two man job) take it down as low as I can, fill it up and repeat until the fluid cleans up. I do that around 40k.
    Not to say that the above is not correct, but I have great success with this.
