4x4 service on AWD

thats not exactly how the numbers work. if the system is 11qts and you drained out 4qt, put in 4 new qts yea thats like 36.7% or whatever, when you go do another 4, your also draining some new fluids as well, so its not like 2/3 new its more like 1/2 or so.
its still better thing nothing. like most say only way to get most of it out is with a machine flush because its pressurized and i think most require the car running.
if you do it the method in the DIY video's i would say 2 flushes the way he did it would be close to completely new, but it will require like 20qts.

I personally would do it twice and then call it a day and do it again in 2 yrs or 30k miles. The manual doesn't even call for atf drain at 4 yrs/30k miles so if you are doing it before that interval I think thats safe enough.

i would put it more or less on driving style then mileage or years.
if you do a lot of highway crusiing you can go longer since the trans isn't shifting or anything its pretty much in 5th and stays. if you do a lot of shifting in traffic and then go high RPM, which people do then you might need it more.
twice every 30k is good for more people.

What size allen wrench is needed for this? From the pics, it looks like i'll need an allen-headed socket to remove the plugs. Anyone know the size?
I want to try to tackle an oil change, both diffs and the xfer case this weekend, but want to make sure I have all the tools before I toss the car up on jackstands
EDIT: found the rear diff is 10mm HEX...can someone confirm if front diff and xfer case is same?

Transfer Case Drain - 1/2 rachet
Transfer Case Fill - 10mm hex
You'll need 3 gaskets (part #11026-4N200)

Thx.
I watched a DIY on the rear diff fluid change and saw there were two gaskets just on the diff.
Where do i need the gaskets? WOuldn't i need 6 if i were to replace everything or did you just put them on the drains and leave the originals on the fills??
BTW, i am mechanically able...i just like to know beforehand what tools and parts I'll need and what problems to expect.

I'm going to attempt to do the front diff, the rear diff and the transfercase along with an oil change on Sunday.
I guess it all depends on the weather too.
So i'll take a trip over to Nissan/Infiniti in the AM and pick up 5 of those gaskets and pick up a 10mm Hex socket....and see if i can find a good fluid pump.

Well, i did the front and rear differential and oil change today.
Diffs were easy. I could prob do it again in half the time now.
Front differential was clean @46K miles. FLuid was still clear and yellow. Rear diff was a brown color, so it was def due for a change. Both drail plugs had tons of crap stuck to the magnets. I'll prob redo the diff @ 30K again, but go a little longer on the front diff because at nearly 50K miles, it looked like brand new fluid coming out.
I didn't do the transfer case because I wasn't sure i could refill it after I drained. My pump didn't look like it would work on the ATF bottles.
Plus, i was going to use Mobil 1 synthetic ATF instead of the Matic-D, but then thought about it. Maybe i'll go with Matic-D instead, but the guys over on bobistheoilguy.com say to use the Mobil 1.
What methods did you use to fill the transfer case?

I used a siphon pump I bought from harbor freight. Each end has a 1/2 size tube about 3 ft long. I am on my blackberry now so I can't show you the pic. I used Matic D for transfer.

Nope, had to order.
I just reused the old ones. I'll check periodically for leaks, but i've been reusing the gasket on my oil pan plug for at least 7 oil changes and it's been dry as a bone. I should prob pick up a pack of those as that won't last forever
The diffs were easy as pie. My A/C belt is cracked as hell, so i'm gonna order up a new one and prob do the belts and transfer case my next oil change in 3000 miles. I'll be doing that one in a friends garage.
