Thanks, helpful vid. I’m replacing the transmission in my 99 Dakota and since I’ve got the front axle out to get the oil pan out, I figured I’d touch it up.
Mopar makes dedicated oil for the NV3500 transmission if that's what you have, otherwise I'd refer to your owners manual. I've never personally put hands on a manual Dakota, but there's typically 2 plugs on the side of the transmission, 1 lower and 1 higher up. The lower one is the drain, and the upper is the fill hole. Typically, they are 3/8” square drive, or allen socket style plugs, but not always.
How do I switch 4wd out to 2wd? I'm having an issue where it's stick in 4wd. I switch to 2wd and light for 4wd stays solid while 2wd flashes. Is it trying to switch over at this point?
@@phillipclayton276 Try switching in neutral and if that doesn’t work try switching in gear. I’m guessing neutral on flat ground is best. Otherwise you may have an actuator issue.
You’ll have to check your owners manual, it probably says in there but it completely depends on driving style too. And the front doesn’t need to be changed as often as the rear. But at about 70k miles, I’d probably just do front and rear anyways.
ALWAYS loosen the FILL plug first before draining the fluid. If perchance the fill plug is stripped or will not come out you will not be able to fill if you drained first. If that happens the diff will need to come completely out. No fun!
The entire diff would not need to come out unless the fill and drain plugs are built into the differential itself. In the case of this particular truck, there was no drain plug, and the fill plug was only rubber. If the fill plug was threaded and damaged, then the cover would need to be removed again, though. Good point to bring up.

Best part "ah, for fucks sakes" 😆 🤣
I must mumble that several times each day.
Thanks. I am doing this job on my boss's truck at work tomorrow.
Thank you for the video. Is there room for an after market diff cover? It doesn't look like it.
Yeah, it's pretty tight in there. IF anyone even makes a front aftermarket cover for these, it would have to be very low profile and close to stock.
What gear oil does a 2002 dodge Dakota 3.9l 5 speed manual take, and where do I fill n check it?

What gear oil takes dodge durango 1999? For the front and the back, and how much?
I used synthetic 75/90 in the front and synthetic 75/140 in the rear. You could use 75/90 in the rear though.
@@TonyTheTruckGuy thanks.
@@TonyTheTruckGuy thanks.
It seems like impossible getting this diff cover back on
Yeah it’s a bit tight, especially without bumping something and smearing your silicone around lol. That vent port doesn’t help either.
Would you know what kind of diff fluid my 99 3.9L 4x4 would take ?
Not off the top of my head but if you still have the owners manual, it will say in there. Otherwise just google. I’m sure it’s 75/90
When should this service be done i have an 03 dodge dakota with 69,000 miles on it

It would have been nice, if you woyldnt have skipped the most important, and difficult part. Putting the cover back on.
Same as removing it lol

What model is this?
2002 Dodge Dakota Sport
I have a 2000 SLT 4.7. Can't find a book for it online or in store where I am. Do you know if they take the same diff fluid?
Yes, yours should also take 75W-90 gear oil for the front axle. I recommend synthetic. You'll need 2 quarts, as I believe it takes around 1.5 quarts.
Thanks.
The rubber plug is your inspection plug not a breather
Correct, I misspoke
Can you check the fluid level by removing that plug. Is that what it's for I mean?
I only watched to see where the fill hole was and you totally skipped that part.
9:17....helps if you watch the whole video 😂
