Good old ATF+4.
Why? Do you have reason to doubt the vehicle manufacturer's specification?I am either going to use Valvoline Synthetic or Royal Purple.
No doubt, just have read that a lot of people seem to use the Valvoline Synthetic when they flush out their power steering fluid. I have also heard that Royal Purple is a great company for fluids as well. Yes, I would still use the ATF+4 so I wouldn't go against that specification.Why?

ATF+4 has a pretty specific additive package. I cannot imagine there would be a benefit of using one rather than another. I say go for the.cheapest one.Timberline said:No doubt, just have read that a lot of people seem to use the Valvoline Synthetic when they flush out their power steering fluid.

Those with 2002 and older Jeeps often use Valvoline Syntheticd Power Steering fluid... but those with 2003 and newer which switched to the Mercedes steering system must use ATF+4. You can use Valvoline ATF+4 which is a synthetic. Any major brand ATF+4 is fine, most are synthetics.No doubt, just have read that a lot of people seem to use the Valvoline Synthetic when they flush out their power steering fluid.

Have you read the placard on your power steering reservoir cap?Rolf / Jerry - I've never done my power steering exhange myself before and I am curious on how it seems that using ATF instead of a specific "Power Steering Fluid" is okay to do?? I have seen your numerous posts on the site stating that 2003 and on are able to use ATF because of the new steering system but I just want to make sure before I go out and purchase some. Feels strange buying ATF for my power steering fluid but if it is of no harm than I will follow suit. A little cautious I suppose...lol Thanks
Funny you mention that because I have read that same exact thing on how when the power steering system was starting to go out on certain vehicles or just old in age, people would fill it with ATF to make it last a little longer.I am not up on the later models but on older power steering systems on most brands of vehicles,when your power steering would start not working properly many times it would correct it by going to ATF because it was a little thicker and then when it started having problems again,switch to industrial/agricultural hydraulic fluid because it was yet a little thicker
Don't just take my word for it, your owners manual clearly describes all the fluids your '04 requires... go see what it says to use in the power steering system.Yea, I'll check my cap and see what it states but I'm leaning on taking Jerry's word for using ATF+4 since he has mentioned it over and over again to people with a 2003 + Wrangler...LOL
