Use atf+4. It's the same as the power steering fluid. Worked at a dealer for years and that's what Chrysler told us. It's a complete rip they sell a pint of "power steering fluid" for the same if not more then a quart of atf. Do not use typical power steering fluid. Will cause the seals in the rack and cause them to leak.

 

And you don't have to use mopar. You can go to any parts store and use 3rd party atf4.

 

I would NOT use atf+4 for the power steering fluid . Your not saving any money buying atf+4 and These jeeps do not come from the factory with atf+4 in them anymore (and they haven't for years) . That's how the garage destroyed my P.S pump without me knowing about it after they changed a P.S hose and topped it up with atf .

Here's the information from the OWNERS MANUAL

Your new Grand Cherokee requires the use of a new
Power Steering Fluid. This new fluid is specially formulated
to ensure the long life of the power steering system.
The power steering system requires the use of Mopar
Hydraulic System Power Steering Fluid (P/N
05142893AA), or equivalent, which meets
DaimlerChrysler Material Standard MS-10838.

CAUTION!
Do not use Automatic Transmission Fluid (ATF) or
other types of power steering fluids when servicing
the power steering system of this vehicle. Damage to
the power steering system can result from the use of
the wrong power steering fluid.

and Here's the info from the service manual

POWER STEERING FLUID
This system requires the use of hydraulic system/power steering fluid which meets Daimler Chrysler specification
MS-10838, such as Mopar part number 05142893AA, or equivalent, DO NOT MIX POWER STEERING FLUID
TYPES. Damage may result to the power steering pump and system if any other fluid is used, and DO NOT OVERFILL.

 

I would NOT use atf+4 for the power steering fluid . Your not saving any money buying atf+4 and These jeeps do not come from the factory with atf+4 in them anymore (and they haven't for years).

Thirding this. The owner's manual and service manual are both very clear about the fact ATF is not to be used, and it's very apparent if you have both fluids in front of you that they're not even remotely the same.

The WK was designed and its fluids were specced at the height of Daimler's reign-like many other DCX vehicles at that time, the WK rack uses an application-specific PS fluid that not even other Mopar PS fluids should be used in place of. And again, if you've got both fluids in front of you, MS-10838 PS fluid and "classic" Mopar PS fluid are clearly different animals.

The aftermarket has exactly one fluid meeting MS-10838; most of them instead target the older, more universal Mopar fluid (as used in WJs, ZJs, and many others).

If you want to bet $8 or $10 against $1400, it's your money, but it's not like power steering fluid has a 3,000 mile service interval.

 

Agreed, use the stuff it calls for.

My old Dakota used ATF+4 in the power steering and called for it. The Jeep (albeit a Hemi with hyd cooling fan as well) calls for special stuff, use it.

You won't be changing this fluid that often so just pony up and use the proper stuff.

 

Use the Mopar fluid. It was $14 a qt and the system in the wife's hemi gc took just over a qt with a pressure hose replacement. A lot cheaper then a new rack or pump.

 

Thanks for all of the infoT I will stop at our jeep dealer and pick some up.

 

My dealer informed me mopar p/n ms-10838 is no longer supported by jeep.
What do you use now?

 

Your dealer is incorrect. The part number changed (I'll go dig around in the garage and see if I still have a partial bottle), but fluid meeting the MS-10838 spec is still produced and available.

It's not hard to look up—if you've got your owner's manual, the parts system will pull up the new part number from the old one in there. Or if the guy at the parts desk isn't a total idiot, it'll come up in a year/make/model lookup.

 

This is news... but makes sense. Chrysler probably does not have exclusive rights to the "formula" nor is allowed to hide the ingredients any longer. Mopar International shows a cross reference from US PN: 05142893AA to Int. PN: 68234631GA for MS-10838 spec fluid: http://www.moparinternational.com/assets/maintenance/english/pdf/Cross_Reference_Guide_19Dec2014.pdf. Searching on that new p/n, I just found a link to the SDS on Mopar International: http://devcn.moparinternational.com...al.com/assets/apac-maintenance-catalog/assets/pdfs/en_CN/68234631GA_SDS_ENG.pdf Still no mention of who really makes it aside from stating that it is "hydraulic oil". It would be utterly ironic if this is the same stuff we put in the transfer case just like other Chrysler vehicles use relabeled and marked up ATF+4 in their PS systems. Can anyone validate this information?

 

Hi.
I only wish the MS10838 was the equivalent of $14 a bottle here in the UK.

The jeep dealer charges £59 for a litre bottle.

Not exactly sure what you mean by you wish MS10838... You mean it is more expensive, or you don't think it is the equivalent of what Jeep sells?

If you see my post above, in Europe your best bet is either Mercedes, or Pentosin.

Where are you located?

Quick search on Google shows UK options.

Because Jeep is a bit of a rarity there. Find the compatible Mercedes branded fluid and I bet it'll be much more reasonable.

 

Interesting thread. What other DCX product lines used this fluid? The LX series (300, Magnum, Charger, Challenger) all use the ATF+4 (MS-9602) type of fluid and all are rack and pinion like the Jeep

 

DCX products with hydraulic fan



Jeep CRD Grand has a hydraulic driven cooling fan that runs off same pump and fluid as power steering system.

Apparently 3rd gen viper and some Cummins diesel also have.

 

Mopar MS-10838 only when called for

Hello, my wife and I are currently doing some maintenance on her '07 GC 4.7. While I was getting diff fluid I bought some power steering fluid as well. Not thinking anything of it, I was getting ready to drain/fill it last night and noticed that it takes, http://www.jeep4x4center.com/mopar-...mopar-hydraulic-system-power-steering-fluid-1-quart-32-oz-bottle-5142893aa.html

What I purchased is this,http://www.amazon.com/Prestone-AS261-Power-Steering-Fluid/dp/B0002JN182

Will the prestone fluid work or do I have to get the mopar hydraulic fluid? (NO!)

Thanks in advance,
David and Tori

As a reference you just use MS-10838 when called for on vehicles with the hydraulic fan. ATF+4 will pooch the fan, and it is $1000 or more to replace.

 

New Part Number

05142893AA part number has been superseded to 68234631AA.

The 68234631AA fluid is the same clear amber color, same viscosity & smells exactly the same as original.

I had to call around to several dealers before I finding some in stock. This stuff is becoming rare.

You can grab some at: morris4x4center dot com

Side note: WJ jeeps call for MS5931 04883077 spec that is no longer available

In April of 04 Mopar released the 5142893AA. At first it was thought to cover just the WK's.
Then in May 04, Mopar released a parts and service bulletin to use the 5142893AA on 01-04 WJ 4.7's

Therefore 05142893AA is the correct power steering fluid for 01-04 WJ 4.7's .

05142893AA has been superseded to 68234631AA.

Note: the 01-04 4.7s, engines also have the hydraulic cooling fan that's powered by the PS Pump!

 

Hi
Motul make a fluid that carries the MS10838 spec. https://s3-eu-west-1.amazonaws.com/...oduct_descriptions/technical_data_sheets/81485/MULTI_HF__28GB_29.pdf?1492017713

I would be happy to use most any central hydraulic fluid in my 3.0crd.

 

Speaking specifically to the OP... YOURS uses ATF+4.

the hemi with the hydraulic fan uses the fancy mopar hydraulic fluid. ALL others use ATF+4. Notice the one person with the damaged pump by a shop not paying attention has a hemi... with a fancy hydraulic fan. The 4.7, does not, nor does the 3.7l speaking for the wk (there is a hydraulic fan on the 4.7l in the WJ).

Unfortunately, I would love to back this up with the owners manual or service information but both ONLY call out the MS-10838 (which is, if for nothing more, proof of inaccuracy). I have worked on these products for 10 years a portion of that at the dealer. The fluid colors are red (ATF+4) in the non hydraulic fan systems or clear/amber (ms-10838) in the hydraulic fan systems. My 4.7l is red (ATF+4), as was what was removed, and no dead pumps yet (with 280k miles).

fwiw, there are a couple manufacturers that call out that they meet or exceed the ms-10838 requirements for those that need it.

The OP has long since bought whatever fluid for their original change, but the lookup tool on the morris website (I know, they can be wrong) says you are calling out the wrong fluid for the OPs rig, which would be exactly what others have said cost them a pump.

Are you agreeing that if they have the hydraulic cooling fan, they don't use ATF+4?

Would the special fluid (for the hydraulic fan) damage a non-hydraulic fan system?

 

My 1991 Dodge Ram van uses the same clear hydraulic fluid. It has been around for a LOOONG time. Always read the owner's manual carefully when selecting fluids.

 

So... I have wanted to look into it a bit more. It just hasn't happened. I am partially wrong and partially correct. To clear the air, the fan is NOT the only determining factor.

My correct statement would be, on a chrysler, if ya have red power steering fluid, it is ATF+4. If ya have clear, make sure it is what is specified. Furthermore, dont ever change fluid colors! If its clear, keep it clear, if its red, keep it red.

I popped the hood to do a trip precheck and felt like a bag of ***** when I saw the special sticker on the side of my power steering fluid reservoir telling me to top it off with MS10838 fluid.

There is already enough questionable information on the topic, I don't need to be making the waters any more muddy. Please accept my apologies for spreading incorrect information.

 

Thanks so much for your comments, clarification and further research. There are plenty of muddy waters on these Jeeps......and all other newer vehicles too. Always love your knowledge and inputs, so keep it up. Oh, Happy New Year too!

 

Pentosin Chf-11s works for ms-10838 specs. I discovered this by reading about Motul Multi HF which is usually not sold in most parts stores but the Pentosin normally is, if the Motul multi HF meets both ms-10838 and chf-11s specs then it only makes sense that chf-11s would meet ms-10838 specs. I have been using it in my 06 Commander 5.7L Hemi with no problems.

 

I never listen to anyone that says put ATF in the power steering reservoir unless that is specifically called for by the manufacturer...that being said, even my 2007 4.7 commander has the amber fluid and calls for ms-10838 or equivalent power steering fluid.

 

After the incorrect PS fluid led to me spending way too much money on my car because it leaked out of everywhere (long story) I'm very particular about using the correct spec fluid for systems like that.

 

I just ordered the right stuff from Amazon. Not hard to find, but pricey. https://smile.amazon.com/gp/product/B00P182W2K/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

 

I know I am late here but today I started getting lumpy steering on my GC overland which has the electro hydraulic system
Yep Mopar is £40 but they also say Pentosin in the hand book and Kerax Hyperdrive CHF 11S Central Hydraulic Fluid - 1L Litre is about £7 delivered and meets the spec. So I have ordered a litre and will start investigating tomorrow.
There is talk of a recall in USA for 2012 to 2014 but I have had no notifications
Has anyone heard of a power steering recall or is it in process but delayed due to covid?

 

So aggravating!

Even later to the party BUT this forum is extremely helpful, in some areas, and I want to add on to it for others and for relevance.

Jeep now says ATF+4 supersedes and it the correct fluid to put into a 2006 Jeep Grand Cherokee 5.7L Hemi.

MS-10838 is correct for spec I need. 68234631AA is the exact part number I specifically need for hydraulic fluid. When given that part number to a physical Jeep dealership they gave me ATF+4, part number: 68218057AC with UPC: 840984173099 and it specifically says on that bottle that it "meets standard MS-9602". So, wrong? I think they're wrong. But I think others are wrong as well. And I'm not sure of anyone actually using this fluid.

1.) I told them what I need is most definitely not ATF+4 and that I needed hydraulic fluid, and that hydraulic fluid CANNOT be mixed with aTF+4 and that something must be off. They took me more serious and saw I am passionate about doing my own work and know cars a little better than that, but was also willing to learn. They clicky clacked buttons on their computer and saw the 68234631AA (hydraulic) was superseded to 68218057AC (ATF+4) by looking up my vehicle by year make and model rather than going off of the part number. I asked them how that can be and they were not sure. I left. 2.) I came back a week later and inquired again, asking if there was a mistake. Person helping me that time had no idea what was going on and they saw no mistake. They took all 6 in inventory and marked it as 0 in inventory because I told them it was wrong. I left. 3.) I came back a week later again and boom, it was ATF+4 that was auto-replenish-ordered because I had them mark inventory to 0. So now they have 12 bottles in stock. The last parts guy I spoke to (I spoke with 3 in person and 1 over the phone) said all Jeep services done at that location had been using ATF+4 in place of the hydraulic fluid. Not mixing or topping off, but by bleeding and doing a complete flush. "Supposedly" (I have no way of confirming) the fluid wasn't "compatible" because it's not to be topped off or serviced with it by mixing, but the vehicle is fine with it as a fluid if done correctly.

*In this forum I saw one person, Underscore a few posts up, saying "the power steering fluid" didn't work for them, but no other details about what fluid, what happened, or where or how or symptoms. Then one of the very first commenters said a shop mixed ATF with hydraulic fluid and it was a costly repair, as everyone would imagine. --- So I can't find anyone saying ATF+4 isn't right, and anyone bringing their vehicle to a dealership or mechanic probably has no idea what fluid or part number was put into the car. "As long as it's working for now" they're not really on forums giving feedback.

----------

I have a 2006 Jeep Grand Cherokee 5.7. It was hydraulic fluid in it currently. It has a hydraulic fan. The fluid is amber/black at this point. It calls for MS-10838 spec. It calls for 68234631AA hydraulic fluid in particular. If you search that part number online the picture will show the fluid I need, but confirmed sources say the seller/website they ordered from will send you ATF+4 since it's the superseded part and a return is done. Wasting time and money.

This is my spare car and not being driven. My power steering level is really low in the reservoir. When the car is on and driving it is fine-ish, when the car is on and at a stop I cannot turn my tires. I'm assuming since there is fluid in there, and the power steering pump is belt driven the steering is easier when the accelerator pedal is pushed down even a little bit. One of my lines is... soaking fluid. Line part number 52080154AE. It's not busted or cracked and has yet to drip fluid on my garage flor, but soaking wet with fluid and get your finger dirty and wet when touching it so I know something is off about it and it needs replaced. I was just going to top off fluid, (hydraulic fluid I cannot find anywhere), but now I need to replace the line and might as well do an entire power steering flush since it's only a quart of fluid and 16 years old anyways.

The only kicker I keep having is I CANNOT FIND THE OEM MOPAR FLUID as the dealership told me it was discontinued awhile back and not sold in their particular location since 2019. They didn't have any further comment or suggestion.

I might just end up having them doing the service I need and holding them liable if I can get something in writing as I will have the line in hand that I need replaced, and need them to do a flush and service of refill.

***I am still scouring forums and groups to see if anyone has any rock solid direction to point me in, or exact fluid I can order, but so far I just have recommendations. Those being the
0.) "05142893AA part number has been superseded to 68234631AA" written by ReinArson on page 2, but that's no longer any help since it's outdated and that's the part number available.
1.) a000989880310 Mercedes fluid that someone on Youtube has used, (today actually, May 21, 2021)
2.) Pentosin Chf-11s that RedBeard pointed out a few posts up.

Those 2 may meet spec, but I will have to verify. I will be somehow calling or emailing or communicating with Penosin and Mercedes to see if they haveany knowledge on if it meets spec. This is all just terrible. All this for an absolute necessary fluid that they recommend changing out every 10,000 miles or so. Like c'mon, people have gone 10,000 miles since they discontinued this. I am so fed up.

 

*In this forum I saw one person, Underscore a few posts up, saying "the power steering fluid" didn't work for them, but no other details about what fluid, what happened, or where or how or symptoms.

That was in my other vehicle, a Toyota Celica that was imported from Japan by the previous owner. PS fluid was leaking out of every single joint in the system, multiple parts of the pump, just dumping fluid everywhere. Long story short I paid a shop to rebuild the whole system, which spiraled into a full engine rebuild since everything was out. I got the car back (a couple years and many thousands later) and it was still leaking PS fluid like crazy. I went to top it up and only then noticed the cap called for Dexron ATF, not PS fluid. I topped it off with some Dex/Merc I had kicking around from my XJ and eventually the leaking stopped as the PS fluid was replaced by the Dex/Merc each time I topped it up.

That's why I'm cautious with fluids now, and why when the dealer listing gave me the wrong fluid I brought it back and ordered the correct stuff using the part number in the owners manual. If that's truly discontinued now (great job supporting your vehicles there Chrysler) then I'd cautiously try one of the other suggested fluids but definitely keep an eye on things. Worst case plan to just remove the hydraulic fan system and swap to an electric one.
