This Is What Happens If You NEVER CHANGE YOUR FRONT DIFFERENTIAL FLUID!! 

PRO TIP: when the old stuff looks like that, run the new stuff until the next oil change, then change it again. The new stuff mixes with any old stuff still in there so doing a second flush/change dilutes anything remaining and it should be good for another 50K miles.

So easy to do! I'm amazed how much differential fluids get neglected in cars because most drivers just don't know about it! I wasn't even aware of this fluid until recently and I feel terrible but after watching this video I can't wait to get in there as it looks extremely easy. Thanks!!

Make sure to change air in the tires: summer air should be swapped for winter air! 😆 Thanks for the fluid tips! 😎

Wow I can't believe how clean the undercarriage is on your suburban looks like new. Great video thanks big Jim.

You should have made reference to check for a vent plug and inspect it. Your fluid was contaminated with water to look that creamy color

Ive learned and I am currently learning alot from you as I do own a 1994 C1500 Chevy Suburban.. Having alot of issues with my truck though! But I am a fast learner so once Ive changed the starter, battery, spark plugs I wont forget the purpose of those parts

I wanted to give a applaud for the video that was done and only add little extra comments of things that need to be done in better automotive maintance and I agree look at the underside and appearance of the vehicles these videos are GREAT and keep posting them your explanations are excellent for basic repairs people need to learn your a asset to the auto learning audience keep your informational tutorials for automotive repairs and servicing coming so more people can learn how to work on there vehicle in a safe manner. The next video is waited for keep up the great job drive your vehicle knowing it's be pampered the way it should be. one little tip that I forgot to mention is some vehicles require a additive added to the oil that is being installed as basic gear oils do not contain the additive required for older limited slip differentials and some retail outlets selling your oil do not remember to mention it may possibly be required and like most older vehicles they do not have the original owners manual that would suggest the proper lubricant and additive required for that make model and year this is where basic automotive background investigation is required of what type of vehicle parts are in the car prior to the job by giving the manufacturer the serial number they will tell you what type of differential setup the vehicle has in a simple telephone call prior to the job again keep up the great videos

Being a Canadian I am amazed at how rust free that underneath of that truck is! That truck is going to last you a hell of a long time if you keep it maintained! In Canada by the time something is 15 years old it in a junk yard from rust!

I've got an 05' Escalade that needs attention. Thank you for your instructional help and videos. God Bless.

This was a nice video it reminds me of my neighbors suburban which looks a little older than yours but has never had its transfer case fluid change it or has it ever been put in four-wheel-drive. The owner was asking me how to put it in four-wheel-drive I said I’ll get back to you later because I don’t want to open up a can of worms😀👍

Good video. That light brown oil you drained out looks like it had moisture contamination. Nice way of putting the new oil in from the top with a tube. I just subscribed to your channel.

This channel is like a way to get your car repair fix in between Chrisfix videos. Cheers mate.

Thanks. Never knew about fluids in differentials which we should change

Thanks for these helpful videos If you refer to your owner's manual it also tells you how often to change the front diff the rear diff and transfer case you should have a healthy 4 by 4😝😝🚗💨

Keep up the good work Jimmy enjoy your show👍

no one ever maintains the diffs and transfer cases. that’s why i check them as soon as i get a new used vehicle. you should check the vent tube on that diff. water got in there somehow.

For RU-vidrs Hi there, i am all the way from Recife in Brazil, South America, really liked your video, very informative and all, thank you for sharing it…

I am watching the second video on your channel, and I already subscribed ! Great videos !! THanks for showing us the reality.

Exactly what I picture when manufacturers consider them lifetime fluids for "normal" conditions.

You're doing good bro Keep up the good work💪🏼✌🏼

With that age of vehicle it's to be expected that the color would be cream coloured and have some moisture in it. I always recommend driving the vehicle in 4 wheel drive prior to changing the oils in front differentials and transfer cases or ALL wheel drive vehicles prior to draining then flush a little new oil out the bottom prior to filling. The way you did it works excellent also you have NEW Fluid which is important and you showed the way to do a job safe and simple which is the major thin and your explanation to check fill Plug first is the most important tip for first time viewers keep up the Great Videos your a asset to people trying to learn and Mechanics like me who are to affraid to make videos applaud your work

Can't believe ChrisFix didn't post his video on changing front differential fluid when he promised to do so in his changing transfer case fluid video. You earned yourself a subscriber

Jim! I remember when i replaced my front and rear fluid when you uploaded the rear diff video. My front diff didnt even have fluid in it!!! And it didn't even make noise at all.

Love the videos keep them coming. I am a guge fan of those GM trucks, the two you have and the Silverados.

Thanks for your videos. Please add some reference shot to your future videos, that shows where the front diff, or where the transfer case is , in relation to the car.

Never thought I had to change my differential fluid at the front until I checked the manual and says I'm long overdue. My suv is 10 years old and only got through about 50k miles, it looked dark so its great that I changed it for less worries. Thanks for sharing this!

Jimmy, love your channel.Keep them coming. I have had my suburban for 25 years and I have decided to keep the old girl alive as the price of new ones are out of control and not well made anymore. I did watch your cluster work on your wife's car but it would be nice if you can show on that 95 Sub. No one fixes this cluster that I am aware of and the new motors are getting harder and harder to find..

Very nice, I'll be doing that this week

You’re the best Jimmy keep it up thank you👍🚗

I changed mine at the dealership 11 years ago. 1995 suburban🚗

Great vlog!

What a fizzer , just can't help but love the facial expressions 🤪

That fluid looks emulsified to me. Might want to check your vents (if any) in your seals to see if your getting water into the system.

Good information Thanks

Your suburban looks really good on the under side.

EXCELLENT VIDEO!!!!!

Great job my friend.

Great video man thanks

late last year I had the front and rear diffs, xfer case, and auto trans fluid/filter changed on my 2004 chevy pickup. I had the rear diff and trans fluid/filter done several years ago so it was a second time for these.

Ok ok ok, you’ve convinced me to change the Diff fluid. Before I do so on my 94 Suburban, word on the street is not to use synthetic pre 1998 or with any additives. Thoughts?

I just did a drain and refill on the front and rear on my 2001 Chevy Suburban. I'm the 4th owner and no papers showing anything about them being done at 100,000 miles,much less at all. It had 151,000 miles at the time of purchase. The rear looked normal,the front was gross but not a milkshake. My transfer case requires the GM Specific fluid which i bought online. I plan to drain and refill that in a few days,because i also don't have papers showing that was changed. All 3 levels were good and the 4wd works great. i just don't know the ages of the fluids and i want to be safe.

i changed my rear diff oil for the first time in 20 years (227,800 miles) and it was still golden brown

Informative vid... but all I could think of was, ChrisFix's father has a youtube channel now?

Would be a good idea to drop the transmission pan and do fluid and filter.

Hey 1road Jimmy make sure you keep them videos coming A..

I have a 98 k1500 I bought recently and I’m going through all the fluids n suspension. I’m doing my Transmission flush n fill like you did soon. Already did the rear diff. Yikes on your fluid! Someone mentioned a breather cap? Where is that located? I don’t see anything on mine unless I need to look again. Great tips.

Going to pick up a 06 350z this weekend, first thing I'm doing when i get it home is change every single fluid I can lol

I love listening to this guy talk ... u won a subscribe for me lol

Love your Videos ! Have you ever flushed your brake fluid ? My vehicles are dirty looking that my next project !

Did you ever get around to changing the oil filter with the magnets and cutting it open?

Hey there Jimmy! I love your channel. Question… Have you noticed any difference after going to the Lucas? quieter? Smoother? Gonna use it on my rig and was curious. Keep the vids coming, we love them.

Readers, keep an eye out for the white plastic washers under the fill & drain plugs. They can easily get lost. I just changed the front diff fluid in my 21 year old K1500. It looked very much like chocolate cocoa. By contrast, my transfer case fluid (Dextron III) looked fine. Thanks.

I’m amazed how little rust is under that vehicle. If that was an eastern or northern car it would have a thick layer of flaking rust covering the entire underside.

I liked the end of the video when you say 1 ROAD 🤣🤣 unbelievable look at your face and the way when you say it. LOL 👍👍👍👍 Keep going bro

Have a question it’s 2003 Ford Focus automatic front wheel drive 183,000 never had transmission fluid our filter changed as far as I know. I heard rumors that if you change them now it can create problems? It runs fine but I’m slowly working on changing all fluids and parts. What do you think I should go for it!

Any issues after the change? Do you think its safe to change a 97 4runner Ltd 240k differential oil if it has never been changed before? Everything works well now.

Hi there when you change the rear and front differential oil, what's the difference of the quality of driving? is there any upgrades? Thanks

My friend has a 1998 frontier with 200k and never changed the diff fluid till a few months ago

wow that was dirty fluid. Good info

I always replace those old/hard nylon washers with copper washers.

That looks like a sideways differential. Darn those independent front axles!

I just changed my 08 silverado front diff fluid, I just bought it with 170k, pretty sure it's the factory fluid.. it was metallic slushy

You need to either let the vehicle back down before you fill it or recheck the oil level after it's back on level ground.

Love your videos. So got a question for all cars front differential are also standard. Sorry still newbie and learning

How do you check it to know you need to replace it? Just let a bit drain out and replug it?

I bought a truck from a guy that barely knows where the gas tank is filled. When I started looking around I discovered that almost zero maintenance had been done....like changing the oil. I discovered on the day I was going to test drive it it was a quart low and blacker than my soul. He had just taken it to Midas who charged him to change it but didn't. When I checked the differentials and transfer case fluids I was kind of shocked. I know it's an '01 Ford but, I've never seen fluid that looks thicker than the foundation my daughter uses. It was like ball joint grease. Since then I've been going through an inch at a time when I have a minute. It's not in terrible shape. It's just never had things replaced like they should have been. Getting the rusted in fuel filter and PVC valve (just really stuck) out was a lesson in patience. Plus I had to ask my son for help for a sec....he had better upper body strength.

The thumbnail is me after Taco Bell

Personally, I think you would benefit MORE by adding magnetic drain & fill plugs.

My 1997 Suburban 4x4 manual doesn't show a gear oil change schedule. It only says to keep them at the required levels. Water contamination would be another matter though.

Is there front diff fluid on all cars?

Wow mine looked nothing like that in my 14.. looks like moisture in the fluid..

Thanks

changed it on my manual Yaris .. i used synthetic 75w90, the old fluid was actually clear , i doubt someone changed it ... 2007 yaris , fluid was clear.

👍👍, you do not want skid marks on ur front diff. Always keep skid marks at the rear

l think you had a bad diff breather/vent valve or case seal. The color of that fluid indicates that water was getting in. The new fluid will get the same as the old unless you fix that.

Did you change out your muffler bearing

A result of driving through deep water and getting it into the differential vent or through worn seals.

is the car running OK now after the Differential fluid been changed

Does that truck have diff breathers? Have you thought about relocating them higher?

Whats up jimmy👍

That happens too when you warm up your engine and not drive long enough in freezing temperatures.

do you actually dump the fluids in bags are is that just for visual purposes

Is front differential and the transfer case the same thing?

Can you change the oil again. Because I believe the transfer case and the differential case still have old oil.

This guy looks like that neighbour that look at you from their front yard and shake his head side to side when you try to fix something in your car hahhaha

Is a new washer desired for the case?

Looks like water got in there Edit: I'd check for a breather valve or hose or something. You've got some other issue. Doesn't make a whole lot of sense that the rear diff fluid was changed at some point while the front wasn't.

If my truck was a 4WD I'm positive this video would've been my resource on how to change the fluid

I just changed mine also and it was this slimey green color also..

Is the 03 suburban sold we haven’t seen it at alll

My fluid is about as bad as yours I'm sure. Would I benefit from doing a flush before leaving clean fluid in there? Or is that not really necessary?

Was this vehicle at some point driven through water that was more than a foot deep? 🤔

What about the blinker light fluid? I can't find the drain plug

That fluid probably still does the job, despite not as good.

So how does it ride?

My question is did changing it make it drive better?

Best part is when he say Holy milky mustard Batman

I got a 02 Jeep library how do you change the rear in.

I did not know u had to change this oil... I'm currently sitting in my car while jiffy lube is doing that change....😅😅😅

Would this be the same for my 99 Yukon bro?
