Great video. I own a 2015 Summit that' giving me a service 4WD message. Dealer wanted to replace Transfer Case. Turns out it was the transfer case control module. Thanks to Google and TH-camrs like yourself. Keep up the good work.
We're these clunking like old floors creaking or just similar to a suspension clunk? Changing my fluid fixed the clunk when turning the steering wheel but i have an annoying creak that's not the motor mounts and the sound is coming from the Tcase/transmission area that i can tell(closer to tcase but hard to pinpoint when in a driveway
@@pjvmusic In our case it wasn't so much a sound but a feel if that makes sense. When at operating temperature it felt like a kid was in the backseat kicking the front seats at each shift. Now that is completely gone.

I am now having this problem, 2016 jeep srt. I feel this when coming to a stoplight or taking off on green light at normal speed. Also I feel it when I turn my wheels all the way. No lights on the dash or extra noises. Thinking about going this route. Any recommendations?
In the grand scheme of things this isn't expensive to do or try. If these fluids haven't been changed in a long time, or ever. It needs to be done anyways. Give it a try. More than likely it is your problem.
You should always loosen up the fill plug first just in case you can’t get it loose after you’ve already drained the oil otherwise you’d be sol trying to fill it back up
Solid point! That is always a good idea. I have ways around that problem and more tools than the average owner so it's something I just don't think about. Thanks for bringing it up.
Just watched your helpful video as I'm doing this job, plus the autobox fluid and filter, this weekend. I'm confused as to why you appear to be using diff oil with LSD additive in the front diff? Unless our 2017 GC SRT is different, it's only the rear diff that is limited slip and needs the additive. This is probably why the rear diff oil was much blacker because of clutch material from the LSD mechanism which is not present in the front diff. We've bought the two recommended Mopar oils with the additive already included for the rear diff but no additive for the front diff. I don't know how much difference it makes to an ordinary open diff if LSD additive is added but it's presumably not ideal? Secondly, the official Jeep workshop manual for the 2014 - 2017 GC SRT states that the transfer box should be "filled to bottom edge of the fill plug hole". There is therefore no need to measure out any particular quantity of ATF. Richard
Thanks for the comment Richard. Don't take this the wrong way but you sound like a very diligent hyper focused owner that is set on making sure you do the job 100%. Not a bad thing, but as a universal mechanic it can be kind of tedious when these scenarios are not always set in stone. There is a lot of misunderstanding IMO about LSDs and limited slip additives and whether it's going to make a differential blow up or lock up or seize or anything of the sort. The reality of it is LSD additives are actually just a friction reducer and they are simply there to reduce friction in the differential clutch packs to provide a smooth driving experience. The OEMs don't want anyone complaining about chattering or noises when going around a corner. Conversely running the additive in an open differential won't do or hurt anything. There's nothing in there to hurt but gear teeth and bearings. Generally speaking all non OEM oil brands synthetic gear oils come with the additive already in the oil. This takes the guesswork out of purchasing most of these oils. I'm not a fan of relying on dealers or OEMs for lubricants and fluids but many owners are which is totally fine. As far as the transfer case thing I think there is no less than 1k forum threads out there on jeep dodge forums on the topic of t case fluid quantity. I've heard several different theories on this. That being said I took the stance of this thing was delivered with a certain quantity of fluid in it that has worked perfectly for 50k miles I see no reason to alter that for myself. That being said that debate went in my head and right back out of it after getting this job done so I don't recall the arguments for or against the different levels. My wife is just happy this thing is back to being smooth as silk.
@@PNW_Car_Mods I'm guessing that the situation is different here in the UK where LSD's are still very rare. Virtually all the synthetic diff oils in the motor stores or online do not contain the LSD additive, presumably because of the extra cost this adds to the product. We used the Mopar oil with LSD additive, which was expensive for the rear diff, and a non-OEM diff oil for the front diff which does not contain the friction modifier and was half the price. We filled the transfer box to the bottom of the level plug hole as specified in the workshop manual and it took 1800 mls of ATF. We left the Jeep on our lift overnight with the gearbox sump removed to allow it to continue to drain and will bolt on the new sump and filter today and then refill. 🙂

like I said in the video. use whatever brand you like but go to the brands website and use their oil finder by vehicle. Yes, the numbers may be slightly different but the oil manufacturers aren't out to blow your stuff up.

AC Delco Tools from Amazon. They have held up incredibly well. I recommend just getting the 3/8s drive. The 1/4 unit is the exact same size dimensionally so it doesn't really make sense. Save money and just use an adapter if you want to run 1/4 drive sockets. I think the pair with a charger and one battery was around 130 but that was like 4 years ago.

Why dont you use for the rear diff the ELSD special additive? It must be mandatory for your model.
