In spite of the fact that Cindy and I work from home and have half a dozen Jeeps that we can and do use as a daily driver, we’ve still managed to rack up 15,000 miles on our brand new Jeep JL Wrangler Rubicon Unlimited. And for us, that means it’s time to do some maintenance. Among other things, the differentials are something I typically service at this time but it’s also a good idea to do if you’ve been spending any time in some deep water. Fortunately, changing out the fluid is super easy to do on a JL Wrangler and it can be done in minutes using a 3/8” drive ratchet.

I took my Wrangler into the shop and they quoted me $500+ to do both front and rear diff fluid change. I found that unreasonable and began searching how to DIY. This video was easy to understand and quickly taught me how to do this in my own garage at a fraction of the cost. Thank you! Keep up the great work Wayalife

[@wayalife]

awesome! Happy to hear our video was helpful to you and will save you a lot of money :)

[@ryangarcia8634]

Yeah, I just called to have 4x4 service done as well they wanted $500+ for the diffs and the TC. Crazy what everything is being charged for! Transmission is next.

[@wayalife]

@@ryangarcia8634 There should be no need to service the transmission for at least 100k miles or more.

[@ericschmidt1987]

The royal purple container makes the change a breeze. Other companies only have bottles requiring fluid pump. It’s messy

[@philobresil6152]

Just called today for maintenance and they quoted me 639$ for front and back, i told them thats is exactly why i dont go to the dealer no more.

[@pines-to-beaches]

Thanks to this video I now know this is arguably easier than a standard oil change - no way I’ll pay 300+ bucks for someone else to do it! Thank you!

[@wayalife]

Happy to hear our video will be helpful to you in the future.

[@mturzanski]

Awesome video! But always make sure the fill plug comes out first before pulling the drain plug 👍

[@MindisJurenas]

Why is that important? Curious..

[@mturzanski]

@Mindis Jurenas encase the fill plug gets stuck or rusted in, ie something goes wrong. Now you've drained all your fluid out and can't get it back in! Being around old farm trucks and heavy duty equipment taught me this lol its not un-heard of.

[@MindisJurenas]

@@mturzanski copy that and good to keep that in mind, I just changed my diff fluids without any issues, Jeep is still somewhat new..

[@mturzanski]

@Mindis yeaman I totally understand my jeep is fairly new aswell . weird stuff happens. It would suck if it was rusty, overtorqued, if it stripped, etc. But it's great to see someone changing driveline fluids. Imagine how many vehicles have never had the diff fluid changed ever. I've changed the fluid a few times in some of the oilwellservicing rigs and support trucks at work its crazy how much moisture can accumulate in 1-2 years Good on ya👍

[@PrussianZwei]

Glad I found your channel. Dealerships are getting way too pricey and look to start to do my own thanks to your videos. Definitively save me alot of money. Enjoy how thorough you are and how easy you make it.

[@alexmckoy8221]

@@prazmeej7972 If you already pulled the cover might as well spray everything down with break cleaner while you’re there.

I’m new to the Jeep community, and have been watching tones of video. I’m a female who loves doing vehicles maintenance myself. I know my 21 year old truck like the back of my hand, with my Jeep it’s like leaving things all over again. Looks like I’ll be serving the differential fluid on Thursday. Oil, oil filter, and both air filters changed this afternoon. I’m only 5’2” and had to stand on the bumper to reach the oil cap and oil filter and one screw on the air filter case. I swear I need a extension ladder to work on my Jeep. 🤣

[@deteriaF82]

Just knocked it out on my Gladiator. Didn't even need to jack up the truck and it felt easier than an engine oil change. Excellent tutorial for 1st timer attempting to doing own maintenance at a fraction of the price the dealer/shop would charge.

Just did fluid drain n fill on my 13' JK 2 days ago. I actually googled it and found your old write-up. I never knew that there was a drain plug on the axles. I did a complete cover reseal the first couple times without noticing it. I do prefer the tucked up drain plugs on the JK axles though, the JL look abit risky.

[@wayalife]

Yeah, the front diff plug is lame. The rear is just like a JK. Glad to hear you found my old write up :)

[@csak30]

Fantastic tutorial. Just got back from a DIY shop and did this myself thanks to the the information provided here. Tried so hard not to laugh while squeezing that royal purple but all I could picture was Eddie laughing at the noises so I couldn't help it! I put 75W140 in the rear since we do a fair amount of off-road driving and occasional towing. A dealer in Vegas did the engine oil change for me while we were on a long road trip and quoted me $1200 for engine oil, diffs, and transmission. Utterly ridiculous. I let him do the oil but I did the rest myself for $299.45 all in and 1.5 hrs of labor.

[@wayalife]

LOL - so glad that we could be of help to you 😎

[@MrCquixote]

ive been startin to look at the amsoil bags of oil

[@normanpowell7217]

Wow! Great video. Was told i have too take diff covers off to clean them out.

[@wayalife]

On older Jeeps without a drain plug, you do need to pull the covers. In fact, on newer Jeeps, the drain plugs have been removed and you have to do that on them too. Either way, pulling the cover from time to time to inspect the internals is a good idea but it really isn't necessary every single time, especially if you have an axle with the drain plugs.

[@SkylerLVN]

Good video! Much appreciated

[@wayalife]

Thanks! Glad you found it to be helpful :)

[@dbierman2001]

Just an FYI in case someone needs to order replacements, they're called drain and fill "plugs", not bolts. Very well made video anyway.

[@v8felon]

Thanks for the drain bolt part #

[@wayalife]

You bet! That thing was hard to figure out. Fortunately, I have friends at Jeep who were able to help me out with that.

[@rcoverlander345]

Thanks again for a great video to help us save some money and learn more about our Jeeps. It's always better to do it yourself so you know it was done right. When you did a video on changing the transfer case, you used a past. Can I use that same paste for the deff plugs?

[@wayalife]

Glad to hear you find our videos to be helpful and yes, you can definitely use the same paste. In fact, I would recommend it.

[@WreckedBrewery]

Great video! Never done a diff fluid change before but watching this looks super easy. I want to do all the easy maintenance myself on my new JL rubicon. Interesting how the M220 rear axle asks for 75W85 in the rear instead of the 75W140 I was expecting. I guess this makes it easier both front and rear taking the same. I have a ways to go before any of this is needed but saving for future use. Thank you!

Hey Eddie nice video, thank u for all u do for the Jeep community, I bought the rock gliders because of u and rancho but I was gonna ask, I wish someone would do a light build to keep weight down on jeeps, that don’t want to turn our jeeps into tanks....

[@wayalife]

So far, I think our build is about as light as it gets. No rear bumper, shorty front bumper and rocker guards and that's about it.

[@carebear2272]

Cool your right, wondering about stuff that’s like alloys, forgot about they way u built yours, guess you can’t replace steel for strength.

[@TheToeIsUp]

Thanks for the vid Scanned the comments so I don't think this is a duplicate question: any need to pull the FAD and drain the old gear oil for it?

[@RichGurska]

Although you didn't mention it, It's good to remind people that the best way to apply the Teflon tape is in the opposite direction of the thread on the bolt, to prevent the lead edge of the tape from unraveling and/or bunching up.

[@wayalife]

This is true :)

[@fuzzd0rk]

Haha! And the shops want $300+ per axle for this? Yeah, I'll do it myself. Thanks for the video. The place that did my re-gear said change the fluid every 25K.

[@wayalife]

Oh yeah, there's no way anyone should pay that kind of money for something as easy as this.

[@Metalgearmadness]

I put a solid axle diff cover on my 8.8. It adds a lot of armor and takes more fluid.

[@wayalife]

The Solid diff cover has a higher fill port and that's what allows you to add more fluid. That being said, the port is placed higher to help you to get the proper amount of fluid in the diff after you've set your pinion angle. That does NOT mean you should put in "more fluid". You should always just put in just enough fluid to bring it to the base of the axle tubes. If you put in more than that, you will have over filled it and gear oil will start to pump out the breather tube.

[@Metalgearmadness]

Yeah I put a little bit more in there, but not even close to the point where it leaks out of the fill tube.

[@aron6998]

The skids you are looking at are made by Rancho. As far as gear oil goes, any synthetic fluid will get the job done.

Glad you enjoy our channel. As far as mud flaps go, I don't think you'll be able to find anything specific for a Rubicon per se but there are lots of aftermarket options you can use such as this amzn.to/2M0PqGL

[@JeepnJohnny]

Thanks for the video. In your description you mention 75w90, but below you mention 80w90. Which one is best for a 2020 Rubicon with Dana 44s? Also, based on my calculations, it will take just over one bottle to fill each diff, so should three bottles do it for both? Thanks

[@wayalife]

You'll be fine with either and yes, about 3 bottles will do the trick.

اخبرني ياصاح كيف أعرف ان المحور الخلفي هو tark-liok او هو عادي؟

[@ourbills9999]

Great vid. I was looking on my 2021 Rubicon JLU build sheet and it says the front and rear diffs have “Tru-Lock”. I see there is also on some Jeeps “Track Lok”,which you note requires the addition of a friction modifier. Do you know if a TruLok diff requires a friction modifier? Thankyou.

[@wayalife]

You only need friction modifier on a differential that has a limited slip in it. If you use a synthetic fluid, it will have it in it already so nothing more is needed.

[@JohnnyLee8355]

Nice video. I'm learning how to change the oil myself too but I have a question, the drain and fill plug holes looks threaded through, what stops the fill and drain plugs from threading all the way in? Would I reach a point where the plugs just threads all the way in? Thanks in advance 😃

[@wayalife]

The bolts will stop and not go all the way through.

[@TheNoisePolluter]

What about the limited slip moly additive that you're supposed to put in to protect against wear and reducing noise?

[@wayalife]

You only need to apply friction modifier IF you have a limited slip differential. And, to that point, synthetic gear oil has it in it. That said, we have a Rubicon and have lockers so it isn't needed anyway.

[@Chickennss]

Jeep went back old school. My 23 sport has no drain plugs in either pumpkin.
