Couple quick things.. Always remove fill plug first!! 2 benefits.. 1 you won't be screwed if it strips after all fluid is drained.. 2 helps the fluid drain much faster... Lastly.. After filling differential.. Take truck for short ride turning left & right several times.. This will fill side internal baffles/wheel ends... Recheck level...it will not be full anymore((very very bad)) Top off one last time & go trucking... Internal baffles are often overlooked in differential servicing!!
My see a leak from the front yoke by the drive shaft area, could that be too much oil or the seal is bad, i tried checking the oil level on that middle plug and oil was coming out but i hurried and closed it back so i wouldn't lose the oil i had, should i check from that top male plug to see it its good with oil?
Good video keep you the good work. I have a question for you, I have 2018 Freightliner DD15 and D12 transmission do I need to change the transmission fluid?
HelIo, heard its not good to do transmission oil changes too frequent, 2018 its too new for it, but ask you mechanic for better advice , thanks for watching sir 🙏
I had a D12 transmission on my last truck and I read the book very carefully. You have to change the fluid and filter every 100,000 miles if you want to keep the truck for a long time. It’s not expensive it just takes a lot of patience letting it drain out. If you don’t plan on keeping the truck then change it at the first 100,000 then every 200,000 after.
Yes. Really, any viscosity is fine, you're trading protection for fuel economy. Thinner is for fuel economy, thicker is for protection. If you look at the viscosity numbers at operating temperature are not as different as you might think. My trucks are summer only severe service, so I use thicker.
Amazon, but really all you need is the 5/8” female square socket. For the other plug, you can just use a 1/2” drive ratchet or socket extension bar, which most people already have in their tool set.
Hey brother my front differential spits oil through the breather hose some times What do you think could be the problem? Im afraid that some day it'll run dry and I'll ruin my differential. I check it often and i have a bucket of oil at home but im just concerned about the leaking. What do you think could be the problem. Anything you could tell me could help. Thanks in advance
@@TRUCKINGTIPSDIY No brother The oil level was ok. I check it often for the same reason because it just spits oil through the breather some times. But you know whay maybe I put too much weight on the first axle thats why the first difference does that,What do you think about that? Like right now i have 34 on the drives but my fifth wheel is moved forward and its not in the middle of both axles. Its more like on top of the first axle. Maybe thats the reason what do you think

Freightliner Cascadia should use 75w90 synthetic gear oil, but you can also ask the guy at the dealer parts once you give him the last six of your VIN.
Just because you do your own work doesn't mean you also can't read up on the procedure from a Service Manual. Also ask questions of knowledgeable people.
why you did not drain the oil from the axle hub, you can not remove the oil from the axle hub from the bottom drain plug on the rear end, the way you did it you should have just filled it from the fill plug because you did not remove any oil from the hub
I just drained and filled both rear differentials on concrete truck that I drive at work. We filled it until it started leaking out the hole in which we were filling.
@@wiredforstereo we didn’t use measurements. we use a simple hand pump on the 5 gallon gear oil pail. The instruction is (after you’ve drained it) to take out the top plug, which is actually somewhere near the middle ; then you keep pumping it until you noticed that it flows out of the hole once it starts overflowing that’s when you know you’ve put enough in. Asking for specific measurements is a little redundant due to the fact that differentials vary in size based on the truck. Just trying to give you the facts. No ego involved.
Couple quick things..
Always remove fill plug first!!
2 benefits..
1 you won't be screwed if it strips after all fluid is drained..
2 helps the fluid drain much faster...
Lastly..
After filling differential..
Take truck for short ride turning left & right several times..
This will fill side internal baffles/wheel ends...
Recheck level...it will not be full anymore((very very bad))
Top off one last time & go trucking...
Internal baffles are often overlooked in differential servicing!!
Btw..we never fill through the hubs...ever
@@williamnixon278 so than you refill through the fill plug, right?
@@jj2751 yes..
But..as stated above..
Get the fluid in the hubs by taking a figure 8 short drive
Good advice brother.
Thank you so much
How often should be change differential oil ?
Straight and to the point. Thanks bro
Cool! The differential oil and the wheel hub oil are essentially the same.
Good video thank you!!
Good job. Thank you
*VERY HELPFUL THANX BRO*
Can you do a transmission oil check/change?
Good video thank you ❤

I little confuse. We can refill oil at the hub or ar differential hole? Is Hub oil and differential are same oil? 🤨
Great video
Where can I buy that oil pump for the 5gal bucket?
Hello, this is just an opinion there's many to choose from.

How many gallons does each differencial takes
Dope
Any owner considering doing this. I changed my diff and trans fluid my last PM as well as the engine oil and truck is pulling so much harder.
Como sabes que el nivel es el correcto? Tiene que estar media pulgada abajo del hoyoo de llenado o tiene que estar arras?
tiene que estar al Ras, puede estas poquito abajo
@@TRUCKINGTIPSDIY gracias
how often should we change differential oil or how many miles?
You can look up recommendations. 250k for severe service, 500k for road. Or maybe 750, I don't remember.
Can you use 75w90 in place of 80w90 in the differentials?
Yes. Really, any viscosity is fine, you're trading protection for fuel economy. Thinner is for fuel economy, thicker is for protection.
If you look at the viscosity numbers at operating temperature are not as different as you might think.
My trucks are summer only severe service, so I use thicker.
Yes 75w90 is synthetic version of 80w90. You would be amazed in the difference between 75w90syn and 80w90 in -20’c temps
80 140 the best
What kind of oil you use in this video?
75w90 synthetic gear oil
What sae oíl you put in the differentials?
75w-90 synthetic is standard.
Where did you purchased that kit?
Amazon, but really all you need is the 5/8” female square socket. For the other plug, you can just use a 1/2” drive ratchet or socket extension bar, which most people already have in their tool set.
The pump can get it from harbor freight for cheaper and it last
Won't a 12 point socket work on a 4 point plug? Or can it handle the torque?
What year was this truck? Can i still fill it from the fluid level check if i dont want to fill from the hub?
jello, this is a 2013, but all differentials are the same, yes you can fill from the level check
@@TRUCKINGTIPSDIY so when i see that fluid is starting to drip out while filling it, thats when i know its full correct?
what type of work dod you do in your differential?, just oil change?, a wheel seal?, or just adding oil?
@@TRUCKINGTIPSDIY i am going to change my dads differential fluid
ok, yes all you have todo is drain it and add oil from the level check
How often you have do it ?? I mean after how many months or miles ?
As far i know, its recommended to change around 250k miles , thanks for watching sir 🙏

Cada cuando es recomendado cambiar ese aceite? Del cascadia
200,000 miles
What kind of oil was used?
Freightliner Cascadia should use 75w90 synthetic gear oil, but you can also ask the guy at the dealer parts once you give him the last six of your VIN.
How many miles between change
im not sre whats the real mileage you can put in, this truck had 500k mile on it
What was the oil density?
Just because you do your own work doesn't mean you also can't read up on the procedure from a Service Manual. Also ask questions of knowledgeable people.
why you fill oil from hubs ?
You can fill from from the hubs or the differential, but filling from hub warranties you the bearings are oild,
@@TRUCKINGTIPSDIY I have a question my friend if I only fill it from the axle the hub won't get any oil after the axle is full?
@@israelaviles5513 It all circulates. It's fine.
why you did not drain the oil from the axle hub, you can not remove the oil from the axle hub from the bottom drain plug on the rear end, the way you did it you should have just filled it from the fill plug because you did not remove any oil from the hub
You do you, this is how i do it
Not that big of a deal. It all circulates.
