This Is What Happens If You NEVER CHANGE YOUR DIFFERENTIAL OIL!!

gotta paint the cover to let others know you take care of your rear end.

The rear differential is often neglected when it comes to regular maintenance. Great video, as always, Jimmy!

It's probably been pointed out already, but whenever you drain a differential or manual transmission it is always good practice to use a brush and some sort of solvent around the fill hole in order to eliminate any foreign from that area. This makes the fill plug area so much cleaner. Great video though, like you say most folks simply don't bother, this is a good lesson to those of us that intend to keep their vehicles for more than 3 or 4 years.

I never even thought about differential oil needing to be changed. I'm going to get a new gasket along with required amount and grade of differential oil and this will be my weekend project. Thanks 1ROAD for taking the mystery out of this job! Great job!

You have the perfect infomercial voice. Can you say, "but wait, there's more!"

Some additional tips. 1. Using a die grinder with a surface prep disk will make cleaning the gasket surfaces a lot easier. 2. Putting thread locker on uncleaned oily bolts will serve no purpose. Clean the bolts and holes and let them dry first. Use that brake cleaner with a spray straw to clean the bolt holes then dry them with compressed air. 3. Put a little Teflon tape or pipe dope on the fill plug or you'll always have a slight seep from the fill plug.

I don't do any sort of mechanical work but I thoroughly enjoyed your video. It was edited extremely well (short and sweet) Your narration was very concise, and matched perfectly with the video segments. And...... NO STUPID MUSIC!!! Thumbs up.

Great video. A couple of points 1) The use of a cardboard template to hold the bolts in the same relative location is a good one. On some older differentials the rear axle vent is through a hole drilled in one of the bolts, That bolt should be on top. Eyeball the bolts to see if there is a hole drilled in one. 2) On newer axles there is normally an axle vent mounted on top of the axle. Clean it periodically. A blocked vent will cause rear diff oil to leak out through the axle seals.

This was extremely helpful. Way to go Jimmy on your first time changing the diff oil as I never knew this had to be changed. Thanks homeboy.

Hopefully everyone realizes you also have to clean the brake cleaner and any residual gunk out of the differential before putting the cover back on. He kinda skipped that part.

I appreciate what you do on ur channel, and even keeping the older videos accessible, just got myself a suburban and looking forward to keeping it in great condition as possible ✊🏽👍🏽👌🏽

Now this guy know how to make videos you actually wanna watch straight to the point keep up the good work brotha

“Every day is a chance to turn it all around.” Powerful message even though this is a vid about changing differential fluid. I appreciate your content 1Road.

If you've got 4 wheel drive, your transfer case needs love too. Dont forget

I never thought how important changing the differential fluid would be. Thanks so much. Just changed my Diff fluid. at 80K miles. Your video covered everything. You Rock Bro !!!

Better to not spray down the inside of the diff with brake clean. The new oil will actually do that for you as you drive. Brake clean washes out the oil from the bearings and seals, possibly running into the axle tubes. That is detrimental to the new oil install.

Gotta love the smell of diff fluid in the morning lol

As a mechanic, Ive cussed guys like this in my head many times, while trying to remove bolts that they have drenched in loctite, that did not need loctite at all. Like these rear end cover bolts. They aren't going anywhere genius!

I'm 63 and have done ALOT of mechanic work in my lifetime. The FASTEST AND EASIEST way I have found to clean metal surfaces is a wire wheel. Bench mount, drill mount, angle grinder, doesn't matter, just don't bear down super hard, let wire wheel do the work. I use this method on almost any metal surface ( including aluminum ) and have never had any problems. Heads, engine blocks, name it. Again, let the wheel do the work, don't use alot of pressure. The gasket material is much softer than the metal, with reasonable care you will not cause any damage

The first diff oil change i did on my 02 defender was an eye opener. It was like grease it was so used and old. Like i could actually hold it in my hand... Amazingly no visible damage done.
