Just wondering for those of you who have changed the oil was how to do it.. never done it before and was looking around under the truck.. do you have to take the whole cover off or is there a screw that needs to be undone to let it out.. any special tools needed o anything.. thanks..

Just a good ratchet set and some patience. :)
I'd recommend getting a small wire brush. It makes
cleaning the old sealant much easier. Make sure you
cover the gears with a piece of canvas or shop towel
while you clean off the old sealant around the gears.
This will help protect from getting the old sealant on the
gears.
After you get the new sealant on let it skin over for
about about an 1 1/2 hours and then refill. Easy job.
You can do it. :)

Don't they have a rubber gasket that would make it easier?

you can purchase rubber gaskets.. i got some from duragaskets.com but you still need a thing coat of silicone to make it stay on there.
this is an extremely simple upgrade for the do it yourselfer.

Its easier to get a hand pump with a hose from Autozone for less than $10. Takes 2 mintues to empty the diff. Then you reverse it and fill it back up.

going to have junk on it and you definitely want to clean that out when
you add fresh oil. :)

That just sounds like a bit of overkill. Its a differential, not an african violet. You used to not even change the gear oil till 100K miles in them.
The only time I ever change the diff oil is either to replace OEM with synthetic or I think I've gotten water into it from off-roading. (Probaby if I towed things too, but I dont).
Do it how you want, some people are paraniod, I'm not. Never had any problems.

http://www.worldsbestoil.ca/Amsoil-Image-Files/g2039_250px.jpgI agree with Sils, if you are going to change the Rear Diff oil might as well do it right and not Half Azz'ed:thatfunny or as we call it shade tree. Using the pump is the easy way out but if you want to do it RIGHT I would take the Diff cover off and inspect it. You can't inpsect the gears and the bottom of the diff with a pump just keep that in mind if you decide to take the easy way out.
Don't forget if you have LSD (Limited Slip Differential) you will need the special additive for it or you will screw the clutch packs up in the cluster.
I peesonally would use a razor blade to get off the old silicone and get the High Temp Red. Also check your book it should tell you how much oil you will need and the Gear weight. Good luck and tell us how you made out.

Not if you're replacing it with synthetic, which is what the durango came from the factory with.

Not if you're replacing it with synthetic, which is what the durango came from the factory with.I've never heard that before cause I havent kept my trucks long enough to have the Rear Diff changed in the past 6 years..... Unless the synthetic has an additive already for both LSD and Non LSD.
By the way cool pics in you Dirty pics link there Gone2. Most of the places here in Florida are flat but alot of mud. I see you are running 33X12.5 by what 16's?
I am looking to go to 35x12.5 x 20 either the Nitto Mud Grapplers or the Toyo Open Coutry M/T caue it seems there isnt a wide selection of good mud tires in the 20" rim.

Do it how you want, some people are paraniod, I'm not.A few people on this very board have found pieces of their clutch
pack and differential in there when changing the fluid.
This can happen. There is no pump that can remove that and
you'll be riding around with that and the gunk in there. This would
cause more damage.
Btw, the magnet is usually clogged with a bunch of crude. This is
mostly the very small metal shavings that comes off from factory.
IMO, it's better to clean it out and see what's going on in there.
If that's being paranoid.... I'd rather be paranoid. ;)

I know the Mobil1 says on the bottle the additive is not needed. I think its just because its more slippery. Their website says you may have to add the additive if the clutches still chatter. I've never needed to add to Mobil1.
I had a '95 trans am that wanted you to change the diff fluid at 10K miles. I called BS. Sure enough, at 10K miles the LSD started to howl. Found when I changed to mobil1 the scheduled 10k howl quit.
I've got 15" wheels on my truck. They barely squeezed over my brakes. I wanted more rubber between my rim and the ground and also the tires are plentiful and cheap.

Of course, the D does not have limited slip so no need for any additive.

Ah ok....... I would add the additive just to be safe...... like the old saying is better safe then sorry.
15" rims..... seems kinda small but I bet they are alot cheaper then the bigger rims to replace the tires. I want to stay with my 20's cause I like the bigger rim, some of the other DT Members think I should go to 17" rims but I want to stay with the 20's since it is my decision to buy the tires. Sorry if I am getting off topic here.

You mean your's doenst have LSD or the Durango in general?
I am almost certain they had LSD as an option in the durango's.
Yes you are correcting in saying if you dont have LSD you dont need the additive. :D

I know in 97 which was the 98 Model year they put LSD in the Durango SLT+ and it was an option then. I just went to the Dodge web site and looked up for the New Durango and not sure if it is cause it doesnt specify other then this on the limited ....Corporate 9.25 LD Rear Axle ... Not sure if LD means limited slip or not but why would they put a 9.25 rear axle if it doesnt have limited slip as an option.... seems kinda stupid to me cause the 9.25 will take an LSD cause thats what I have in my 04 Ram.
the 9.25 axle isnt even an option on the other 3 models.... Very Strange and I am not sure what the diffrence is cause I am not a Durango person and have been out of selling cars for a long time. By the Way Good Catch.

If it is then the Dodge Website is wrong when you try to choose the diffrent options. Man I think we stumbled upon a screw up on their website. LOL:thatfunny

By axles, I mean gear ratios. The 4x4 only comes with the 8.25 rear axle. The 9.25 LD (light duty) has a heavier torque capacity compared to the 8.25 and is also used by the Dodge Ram 1500 trucks. The 3.55 gear is standard and 3.92 gear ratio is an option on all 04-05 4X4 Durango's. I think the term 'corporate' refers to 'Dodge' made vs. Dana.

4X4 has nothing to do with the rear end as far as I know. Mine is 4X4 and it has the 9.25 axle with 3.55 rear end. Just changed out all my fluids last weekend with Amsoil. Called dealer and verified no limited slip is needed, the AWD system with traction control replaces the need for Limited Slip. So perhaps if you don't have traction control, this is different... <shrug>

The dodge website states that the 9.25 LD is not available for a 4x4, only the 8.25 with a 3.55 gear or 3.92 as an option in the 4x4. Maybe their website is wrong or has changed for the 2005 year model.

Interesting. Perhaps they don't expect 4X4 users to tow? Isn't the 9.25 a stronger rear end? Oh well, likely they both meet their towing specs. ;o)
