    Default WJ power steering flluid, mopar only?

    I have to go to the dealer to get 4 pints for the NV247 and i noticed my power steering is leaking and i need to fix aswell.

    But jeep and wjjeeps.com says i need Mopar P/N 04883077 Hydraulic fluid/power steering fluid (MS5931) (MS5931 IS THE ONLY FLUID THAT CAN BE USED FOR THE POWER STEERING SYSTEM. NO EXCEPTIONS!)

    can i use something off the self or only Mopar for the power steering?
    does anyone one know how much is need to flush the entire power steering system?

    its a 02 4.7 limited
    Thanks

    The brands in local parts stores and Walmart list the specifications that they meet. Pick one that has the spec number you have.

    I'm running synthetic in my 02. I just got a fluid that met mopars requirements. Been fine since 06 (knocking on wood).

    I use Mopar P/S fluid only.
    I think the reason is that you V8 guys have hydraulic cooling fans (that are operated off of the power steering pump) and it is important for the fluid to have the right viscosity, additives, etc.

    I wouldn't risk my P/S system just to save a little $$$ on the fluid.

    There once was a Valvoline synthetic fluid that said it met MS5931 specs, but I can no longer find it.

    I just get the Mopar stuff now.

    I am on my third power steering pump in a little over 100k miles for my 2004 Overland.

    The first time the dealer replaced the pump (at about 40k miles) they put ATF in the system. I did not notice it until I got all the way home (about 20 miles). I got pretty upset at them and had to show them the TSB that WJs require the MS5931 fluid.

    They reluctantly flushed out the ATF and put in the correct stuff. When I got back home, I sucked out and flushed as much as I could too. I was so mad at the dealer at the time, I refused to buy the fluid from them, so I found the Valvoline stuff and used that for flushing and refilling.

    At 99,800 miles, I took the Jeep in to get the broken exhaust manifold bolt repaired before my warranty expired. While it was there, they said that my power steering pump was too noisy and they wanted to replace it while the warranty would still cover it.

    This time they did use the correct Mopar fluid.

    Conclusion: That Valvoline synthetic fluid possibly may not have been so good. Or maybe it was just a slow seller and the stores don't stock it anymore.

    Edit; I just went out to the garage and found the bottle of Valvoline Syn Power fluid. It says it is a synthetic blend with conditioners, helps stop squeals and leaks. (that may be the problem) On the back it says "Meets GM part number 1050017 (Spec 99815010), Chrysler Spec 5931, Ford Spec M2C128C. NOT RECCOMENDED FOR HONDA VEHICLES". The Valvoline part number is VV056.

    Thanks for the help,

    I am going to check if the fluid is in any stores around me tonight.

    This morning i noticed what looked like a new stain under the jeep so i looked closer at it and the fluid is leaking more. check out the mess it made in the engine compartment.

    Attachment 31042

    Now i am just trying to figure out if the hoes or the pump is damaged. any ideas on which one could be the problem or what to look for?

    anyone seen any writeup on fixing the power steering in a wj?

    Thanks

    I topped off with both house brand p/s fluid & Lucas p/s additive with no issues so far.

    Redline has made a P/S fluid that meets the Mopar 5931 spec for several years now. Amsoil just brought a P/S fluid, that meets the Mopar 5931 spec, to market several months ago.

    The 4.7 needs a special hydraulic P/S fluid. The 4.0 can use any old P/S fluid.

    I'm not sure whether you can get the special hydraulic P/S elsewhere other than Mopar (ie dealership)

    yea cant find any in local auto shops, the closes i have found online is Valvoline GM, Ford and Chrysler Power Steering Fluid but can find it for sale anywhere.

    Now i am just trying to figure out which part or parts i need to replace.
    It looks like the leaking is coming form Hydraulic Power Steering Hose since i see fresh fluid on it and the mesh wrapped around the hose is covered in the fluid too. but i also see fresh fluid right next to the were the fluid reserve is so don't know if its just the hoes or both need to be replaces.

    I don't know if anyone has had this problem before but i see that auto zone has something parts cheaper then mopar but I don't know if the auto zone parts are any good quality wise. I don't might the extra price but are the aftermarket marts anygood?

    Hydraulic Power Steering Hose: auto zone for $30 vs mopar $80
    Power Steering Return Hose auto zone for $18 vs mopar $28
    Power Steering Pump Pulley auto zone $15 vs mopar $25

    I have to go to the deal anyway for the fluid so just want to know if i should get OEM or aftermarket parts to fix the power steering parts?

    Doesn't the 4.7 and the 4.0 use the same pump? You shouldn't be losing power steering fluid so if you are the first thing is to find the leak. I haven't needed to top off my system since owning the vehicle. I have changed the fluid a couple times after the first pump died but other than that it maintains a level.

    I believe the4.7 and 4.0 have the same pump just with the 4.7 the power steering pump has something do hydraulic cooling fans.

    I believe i found the leak coming form the Hydraulic Power Steering Hose. just don't have the fluid to put in there if i swap the hose yet and i don't know if the pump is broken. Tomorrow i am going to clean up all the fluid that is allover the hose, pump, and all the other parts that are greasy from the fluid with engine degrease and break clean and see if i can track were its coming from.

    when you changed the fluid how many quarts is it to flush out the system to replace all the PS fluid?

    anyone know if the aftermarket parts are any good or should i just stick with mopar for replacement parts?

    People who have had to relace powersteering hoses on the 4.7 have discovered that the correct replacement is a dealer only part. The fitting on other parts stores replacements are wrong. It would be a good idea for you to do a search for "power steering hose" on the ZJ/WJ Forum. There are a bunch of threads that could be of help to you.

    BTW, the part numbers for 4.0 and 4.7 pumps in my WJ parts catalogs are different. I believe that you can count the pumps being different.

    Thanks for the info, i found a few thread that helped but still looking into 2 things. how to flush the entire PS system and how many quarts i will need to fill it after.

    your right on the pumps they are different for the 4.0 and 4.7

    just spoke with the stealership in my area and they all want $9.50 a quart for MS5931 PS fluid.

    Is this the normal price or are they really charging me allot for the fluid?

    That sounds like a pretty normal price for the dealer part dept.
