- Fix It Right! - Differential Service (S1E1)
Demonstrated on a 2005 Jeep Grand Cherokee 4WD.
In this video, we demonstrate how to perform an oft-forgotten but important maintenance procedure: servicing a vehicle's differentials. Most vehicle manufacturers suggest that this process be performed on regular intervals - usually 15,000 miles or one year, whichever comes first - and often after certain events such as towing. Both removable-cover and drain-and-fill differential styles are covered, and the instructions here also cover transfer cases on 4WD vehicles as these are generally serviced via drain-and-fill.
Be sure to check your vehicle's owner's manual for specifics for your vehicle, such as how often to perform this service and what fluids/oils to use.
IMPORTANT NOTE: Please read the disclaimer text at the start of the video before attempting anything shown therein. Take your time, take care, and be safe!
About the "Fix It Right!" video series:
"Fix It Right!" is a series of how-to videos intended to give do-it-yourselfers basic instructions on proper vehicle repair and maintenance. All of our videos show real repairs being performed on real vehicles by real technicians in a real auto shop. (Repairs are filmed and shown with the permission of the vehicles' owners.) Although there may be more than one way to perform any particular repair (and in many cases there are lots of ways!) we try to focus on the methods that will be safest and most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex or dangerous for DIY, or require specialized tooling, expertise, equipment, and/or certifications. Those episodes will highlight the importance of hiring a professional auto technician for tasks that are not DIY-friendly, and demonstrate why such tasks are best left to professionals.

Dude! This video is so 1980s style! I f*cking love it!
I'm just glad the drummer finally got some help.
I am so happy i finally found someone on youtube that gives the tech specs and the right information on how to do things best. please keep making videos!!!!!
My compliments on the music!! Very easy on the ears!!
Indeed - the drain and fill plugs used in differentials and transfer cases only need a light "snug" to secure them. Overzealous use of tool leverage can result in stripped-out plugs, galled plug hole threads, damage to the case itself, and/or a stuck plug that has to be drilled out later.
2000 Jeep Cherokee here...about to do this....good video.....thanks....very helpful.
I think this is one of the most neglected services there is on a vehicle, great tutorial. I used to do mine every two years before I was introduced to Amsoil synthetic oil which is recommended every 50-100K miles.
Highly recommended. Nothing left to imagination, Everything is so clear and understandable. Great Video... Thanks from Costa Rica.
Just a tip, make sure you can undo the top up plug before you drain your diff.
Some differentials use an actual gasket, and others use sealant. The sealants we prefer to use are specially formuated silicone and RTV rubbers intended for use as gasket material, and most of these are "apply bead, torque down, done," as the formulation for gasket RTVs is often self-curing even when exposed to other chemicals. Toyota's FIPG (Form-In-Place Gasket), for example, can skin over in an hour and fully set in 24h while submerged in engine oil.
competent and efficient mechanic! Very easily understood, Thanks
thank you guys tremendously, this is the video i need, and will save me about 400 bucks for differential and transfer case service. very detailed, absolutely easy. keep rocking.
thank you, this was just what I needed. The text makes it much less abrasive to watch than having to listen to somebody drone on.
Great video.. very thorough easy to understand. Hope to see more in the future!
Iridium242 great video I like your style
Great video, thanks!
Good video, thanks! I usually like to make sure the drain/fill hole isn't stripped or has problems opening before taking the diff. cover off, or else one could end up screwed once the casing is drained if they aren't able to fill it back up. Also, most gasket makers require some dry time and curing before complete tightening, just in case some folks don't like to read the directions.
Very helpful! Thank you
Nice video footage but on top of it very Professional job. Thanks
Just spoke with Permatex. Their tech said for front or rear differentials where gear oil is used, ONLY use their 81182 gear oil RTV product. They said that gear oil is acidic and will leak if any other RTV or even The Right Stuff is used. I asked about the anaerobic sealant
and was told NOT to use it either. No Ultra black, red or blue RTV either. Just a heads up guys
GREAT VID! Love the captioning...makes its easier to follow along and pause. Going to be working on my 98 jeep cherokee in the near future
For a 2000 Jeep Grand Cherokee, you'll likely be using hydraulic oil, 75W140 up front and for the rear, 80W90 for normal duty or 75W140 for heavy duty. If your particular Jeep has a limited-slip rear differential (e.g., Trac-Lok), you'll need to add a friction modifier to the fluid - we've had good success with Lucas' gear oil products, which are available as the oil with the limited-slip additive already mixed in, as well as an additive for other oils.
Great video guys. This video made it seem easy for any body with minimal mechanical experience. Keep them coming. Would like to see a video on how to change spark plugs on 06 mustang GT.
Awesome. Thanks once again
Great video. Helped me a bunch!!! Thanks so much.
I love watching my fluid slowly drip out of the rear end. Great to know others think the same!
GOOD VIDEO!!! THANKS!!
very good and well explained video.
well done boys.
thanks a lot !
Very nice. Thank you so much. Big Helped.
Thanks for information
Nice video... The only thing I would change is the order you tighten the rear differential bolts. Should be in a "Star Pattern" to prevent distortion of the cover.
Use a bit grease to drain plug inside before inserting. This will save from (water-leak-dust etc) and increase its life in my opinion.
Get your self a nice brass wire wheel and use that to get the old gasket off. That's what ive been doing for 15 years never had a problem yet.
When I get a new to me used vehicle, I change all fluids, filters, grease, tires- battery if in doubt. Clean fuel system.
Wax and polish all appearance aspects, ensure all features operate as new.
You couldn’t tell my 09 Sierra from new at 80, 000 miles, just getting broken in at a tiny fraction of new cost.
Soon have it as new, brakes and all systems are turn key for next 100,000 miles of motoring down life’s byways.
( I will not however purchase a vehicle from rust belt salt damage, that is simply insane what happens to those vehicles, they are ruined in one years time. You might as well dip them in battery acid. )
When I did my rear differential with reusable gasket, just for extra, I gloss blacked painted the clean cover. Some rubberized frame coat about the frame and man she looks good!
Her ride is solid and tight yet quiet and smooth, love it, 5.3 vortex plenty of power through auto six speed.
@Iridium242 Oh, you will - we're hoping to churn out a new video every ten days or so basically from now on.
Gut video ecxelente
You are good. Job done right!
Good video, good music too. Narration would be better than reading while trying to watch the video. Overall very good! Thanks.
Great video! Thanks for the help.
A big thumbs up
Great video from you guys as usual. I have a 96 Jeep Grand Cherokee Limited and would like to change the vaccume lines. Hoping this is the problem with my air condition doors to the front not working . Probable the doors themselves, but thought I would try this before taking the dash board out as they could use a change after all these years, but it's a sweet running car.
Great video thanks.
excellent video!!
@swampers111 Thanks, and hopefully we'll be filming one of those in the next couple months (when the customer is ready)!
You use synthetic gear oil or semi synthetic? Brand oil?
thanks, guys!
nothing like some slap bass while scrubbing off gasket coverings
very like the video, thank you!
A lot has been shown on the play of the prop shaft for the Lafa niva, But nothing on how to repair?? could any one assiy please.
Thanks a lot I'll do it on my pickup asap ;)
Didn't know anything about the front fluid change. learn something every day .from my Benz to my trucks. I save $$$$$ .Thank you. Note: I'm not mechanically inclined . But viewing your video It feel like I cant go wrong.so fair so good. I did some meager shit!!!! to my Benz and trucks that save me shit loud of money .Thanks.
muy bueno amigo 100 puntos felicidades y gracias por el tiempo
Thanks for the help. Could you tell me how to tell if you have a limited slip, mine is a 99 Jeep XJ.
nice video. thanks.
a bench grinder with steel brush will brush silicone or an old gasket off much faster
I just pumped out old oil and put in fresh .
Very helpful! Thank you. My 2000 Jeep GC's front differential is leaking at the very bottom of the seal, so I want to open it up, replace the fluid, and re-seal the cover. This video definitely helped out, but I'm just curious, what specific kind of oil and additives should I use to refill it? Please, let me know. Thanks.
@djoneab One of our primary goals with this video series is showing how to do the job correctly, as we see a lot of DIYed work at the shop (yes, OSA is a real auto shop) that inspires concern. If you're gonna do it yourself, do it right! ;-)
Be sure to only lightly torque the plug in your transfer case or you will regret it later. It will be stuck forever or possibly crack the case. Just a tip.
Thanks for the vid
All drain plugs should only be tightened lightly. Most people I talk to have never even heard of such a thing as a differential, let alone fluid for it.
How do I fix a leaking upper transfer case fill bolt? The question did not post fully belo. Nice vid by the way. Thanks
Good video, but I gotta call you out. What about putting those rear diff cover bolts on in the OEM pattern and how about using a torque wrench and setting them to the OEM torque spec?
What is the name of the tool you are using to squeeze out the sealant from the tube? Thanks for making the videos for us, DIYers -- Subscribed and liked
Thanks for the video,I have a better understanding on this topic..Should I have my SUV get a replace differential or just get someone replace the parts in the old one...and where do u take this to get repair(Shops)
Is there any added benefit to flushing the diff to clean it out? If so, how do you do that, and with what?
Best bet is to get it checked, it could be a solenoid, a switch, issue with the diff, there are just too many possibilities and not enough information.
Muy bien buen trabajo ecxelente

2:38 what if the gears make noise when u turn the front tire
Hi is it possible to adjusta a differential? i hear a little "clonk" when i change from 2nd to 1st, or reducin gears. I check the cardan (bar) and unions in cross, but i feel like its a thin of adjustment, is there any way to adjust differential play? thank you
Hello, thank you for the video. Do you have a video on how to remove the carrier? I'm trying to remove a Series 3 carrier from an axle I bought out of a '70's Trans Am (10 bolt 8.5") so I can put it into my '79 T/A. My car has the weaker Series 2 carrier that came with 2.41 gears. With the upgrade, I can then use 3.42's with an appropriate carrier (Series 3). Any help? Thank you.
Question. If the backlash is loose and makes the clicking noise when coasting, how bad is that to the differential exactly?
Actually, we use captioning instead of narration so that folks that are following along can pause the video and have the text still be there. It's easier to follow when doing the job. :-)
Hai I have ford explorer 2002 xlt It gives a noise when we accelerate the car.I am go to mechanic he say check differiantial I rechange the oil but the same sound .plzz tell me what I am do now
This process can be performed without a lift, which is why special tools are not required. A lift makes the job easier, of course, but folks do services of this sort at home without a lift all the time.
How to change the plastic cutter between the conveyor and the carbine for the Jeep Cherokee 2012 OneSourceAutomotive
Sounds like Spyro the Dragon music in the beginning lol
P.S.
A "garage" is not required either, but if you got one, use it. Or don't, whatever.
sir i have sound in rear Differential from haft side suburban 1999 what i can do please help me.thanks
hey man can you make a video how to repair or fix the differential of a 99'Jeep Grand Cherokee Laredo 4.0 liter 6 cylinder because it's been making a lot of noise in the back when I'm driving and stops when I slow down. i don't want to take it to a technician because it costs too much and I don't have that kind of money. i want learn this stuff for future reference just in case it were to happen again me. please do a video for the same year, make, and model for my trucki would really appreciate it help me learn. thank you have a great day boss.
Generally speaking, what we film, both in terms of the vehicle and the work performed, is rather opportunistic, meaning that we film whatever happens to come along. We haven't had any Grand Cherokees in that year range in a while. I can't say for certain whether, when, or even if we'll have any specific vehicle come in for any specific job. That said, if a '99 G.C. does come along and the owner wants to heve the differential serviced, we'll try our level best to film it.
Jesus Silva check out BleepinJeep's channel, they have a differential fluid change tutorial on a Jeep Cherokee that used the same rear axle as Jeep G.C. ZJs (1993-1998) and WJs (1999-2004).
Jesus Silva i myself have 1998 Grand Cherokee and I'm also experiencing the rear differential hum you get when traveling at speeds at or above 10mph and gets louder the faster you go.
Good mecanic
what do you do if some bolts are stuck
I've got an '03 Subaru Legacy L AWD, is there anything that should be noted before doing "AWD" instead of "RWD"?
once the cover is off, why would it not be good to go ahead and use brake cleaner on the diff gears also...you know, to clean them to like the cover is cleaned? Just a novice that's never done this. thanks.
The instructions on the back of the tube of ATV sealant say to finger tighten the bolts, wait an hour, then tighten 1/4 turn, then after 24 hours, torque to specs. That's not necessary? You never use a cork or rubber gasket?
Richard Bryan I like your video n style
what is the name of the tool you use to put on the sealant with?
What was the grit sand used to remove the rtv?
Where did you get that drain plug tool?
What did u use to clean the gears????
You can use brake kleen.
can you put a video on how to change blend dors on jeep GK wj. please?
We don't get many requests for that task because people often trade the vehicle in rather than taking on the expense of repairs for anything involving the HVAC airbox assembly. That said, if we have one come in that needs this we'll see about getting some footage.
Thankyou for your replay. i think what you do is verry interesting. Mecanics here in my town rather damage your car then repairing it so i try to repair it by my self
Some people recommend spraying water based brake cleaner into the gears as well, then drying them out with a paper towel or cloth. Do you recommend doing this? I saw that you sprayed it on the cover, but not into the gears.
no special tools required. just a friend that can lift your car above your head for an extended period of time.
That can be done "on the ground" without even needing a jack if the truck has enough ground clearance, but a lift makes life so much easier...
Hello
how much does this service cost???
Two Candies. For You.
How are you
👍👍👍
I had a leak on my silverado 1500 a few months back now they're telling me I have to pay to change the differential oil, is that how it works?
If the differential cover has to be removed to fix the leak, yes, as you'll lose the fluid when the cover is removed.
leaking most of them time mean breather is clogged
Is this process the same for a 2000 jeep Cherokee?
+AHTxStudios It's the same for every differential ever made on a solid axle. Unless you're in the military sitting on 2.5 ton Rockwells or something.
Not for road use you don't weld a diff
You are using a Mopar SAE 75W-140 (API-GL5) ??
How much it goes for rear differential, and how much for rear?
Is it need to add any additive?
Always check the specs for your application, as these should provide fluid types and quantities and whether you'll need to add any friction modifiers for limited-slip differentials.
+OneSourceAutomotive it could be right, but i bought a car without any specs or books..
Just want to know, to use the additive on fron or rear diffs, or both of them?
What type of sealant is better to use?
Several companies make sealants specifically for differentials, as hydraulic gear oil can soften some of the sealants used in other gasket areas. When using any sealant instead of a traditional gasket, always check its documentation/packaging for suitability for use with the fluid you're sealing against.
Is it really required to use brake cleaner to cleanse it... It sounds like too strict..???

I bet this one leaked in no time. Still had oil in the pumpkin that will drain out and contaminate the uncured "IMPROPER" silicone. That is not 81182 Permatex.
