This was a well put together video and I appreciate you doing it. I didn't know they had so many different transfer cases. I have a Laredo but it has High and Low range.
Thanks for the great video! I think the hardest part is removing/reinstalling the skid plates. I have a 2019 Grand Cherokee Limited with Quadra Trac II (no eLSD on the rear diff so no friction modifier needed for mine) and I plan to use your video when it comes time to change my fluids. I currently have 24k miles on the Jeep so the diff fluid changes are coming up soon at 30k. I think the rear diffs that have the eLSD have a small motor mounted on the drivers side of the rear diff, so you can easily tell if you have eLSD.
Thank you , glad you enjoyd it. No I don't believe it is. The Cherokee is considerably different than the Grand Cherokee. The rear diff service may be similar because it has a rear diff but the transfer case may be much different. The Cherokee is a front wheel drive chassis with a 9 speed ZF transmission and 4wd power take off unit. It is postioned sideways in the engine bay like a typical front wheel drive vehicle. Sorry but this video may have similarities but wouldn't apply to the Jeep Cherokee Trailhawk.
I have a 2020 Grand Cherokee Trailhawk, and the dealer spec for the 3 fluids was the same as yours except for the rear. The rear uses the same(Mopar) API GL5 75-85 but they said to mix in this small bottle of friction additive stuff. Now, in your video it sounded like that afditive was already mixed in and ready to go with that API GL 5 75-85w. Thoughts? Thank you.
Yes, the fluid I used already has the limited slip additive in it. It is possible they gave you a comparable fluid and had you add the additive as it is likely cheaper. The Mopar part number for what I used is 68083381AA. Make sure the part number of what you were given match. It may look the same and be a different fluid. Not saying what they gave you is wrong, likely a cheaper alternative.
@@millstonejeepworx Thanks for the feed back. Just checked the print out and they gave me that same part# as you refrenced. The friction modifier they told me to add was Mopar part#431806-AD. Now, since I had just watched your excellent video, I was confused, got the print out and declined to purchase. Will run this by another dealer to double check.
@dgio5052 If you google the part number for that fluid. It says it is for the LSD and has modifier in it. But....double checking won't hurt and gives peace of mind
@@millstonejeepworx Yes, thank you. It was a 'soccer mom' car and has 48,000 on it, so it's probably not that critical. But $230 for fluids, I just want to make sure I'm getting the correct stuff.
Why did you need to change the fluids in a 2019? Did you put that many miles on it? My 2017 now in 2024 is just turning 80k miles, which calls for checking the oil only.
I generally do diff/transfer case fluids every 30-40k miles. If you look online the recommended intervals range from 30-60K miles. At 80k I would be doing the diff/transfer case fluids and would also want to do a transmission fluid/filter change. My choice of interval may be overkill to some but to me, Overkill is Underrated. I personally think that maintenance is cheap especially when you consider these vehicles are 40-50K+
Hey bit of a pickle , do you know what that “fill plug” you thought was for the rear diff was that said do not open ? I thought the same thing and opened it :(
Hey there i have 2011 jeep grand Cherokee Laredo i changed the transmission fluid through drain and then i measured it only came out 3l but jeep manuals says it should be 5l i called dealership they also say its 5l but when i am checking with the Chrysler dipstick level is good by adding 3l only What should i do anyone had any idea ?
@jassdhawan7372 Is it a ZF 8spd? Or is it one of the Chrysler 5 or 6spds? If it has a dipstick and the level checks I would expect it is good. Especially when what you took out matches what you put in.
I have a 2017 Grand Cherokee Altitude. At about 51k or so miles, I noticed some fluid on the drivers side of the front differential. Any idea what could have caused it and how easy would it be to fix?
@KfromtheBAY Is it on the side where the front CV axle comes out to go to the wheel? If so, it could be axle seal on that side. I'm not positive how the axle seals are set up on the front diff. If it is just inside from the axle shaft then replacement should be pretty easy. Remove CV axle, pry out the seal, replace with new one. Some axles the seals are internal making replacement much more difficult.
@millstonejeepworx it's not to the point where it's leaving a puddle on the ground. The spot has just about doubled in size, though, within the last 3k miles or so
I've been looking all over the transfer case housing on my wife's 2016 Grand Cherokee limited and cannot find a model number tag or marking on the housing. Do you know if there is a way to tell which model Tcase it might have?
Best thing will be to go the dealership with your vin# and they will be able to look it up. You could also google Jeep build sheets. I know that with wranglers there are websites associated with Mopar that you can enter a vin number and get the factory build sheet.
Not sure what your talking about. There are multiple options for lift points both front and rear. The front point I used was where the front subframe bolts to the unibody. There are no issues using that spot so far or from any of the techs I know at my local dealership. But I will keep my eye out and thank you for pointing it out.
@@millstonejeepworx those are not lift points in the front, there are numerous comments in the jeep forums where in people have jacked at those bolt points and ended up with issues requiring the replacement of those flimsy brackets. Which warp under stress. Some people have successfully removed & straightened them out themselves.
Yeah, I just noticed that after I read your comment. Never raise the front end by the crossmember brackets. It will slightly bend the brackets, enough to cause a groaning noise as you drive. I did that once, before I knew better and that was the result. The dealer replaced them under warranty. I didn't tell them that I was the one who caused it. 🙂
Both diffs and the t-case should only be filled to just over an inch below the bottom of fill plug hole. Too much fluid could blow out your seals. You can use the short end of an allen wrench as a mini "dipstick" if you will 😂 Great vid though man. Not criticizing your work, just wanted to let others know.
Thanks for the suggestion. I have seen this and done this on other vehicles that called for it. This one I did fill to the fill level and so far have not seen any issues. I have experienced times when diff or cases were overfilled and seen them puke fluid out of vents. I've only ever seen them leak through the seals when the vents are clogged or blocked and they build pressure as they warm up with use.

that garage is bad ass!
Great video, is this process similar to the Cherokee Trailhawk Elite 2019?

great vid i have trail hawk 2014 model where are model numbers for transfer case please
You'll have to get that info from a dealership or look it up via your VIN or build sheet of your vehicle.

I am not sure. I know someone else who opened it and they just closed and snugged it back up with no worries. They haven't had an issue.
Thank you

@millstonejeepworx to me, it looks like the differential case cover is leaking. It does not appear to be leaking out of or around the CV

Those are not Jack points in the front, those are easily damage able points. If it starts making strange noises when you turn, you will know why.
