I am planning on changing the oil in my front/rear diffs for the first time and i have a few questions (I read through some of the other topics, but still unsure) It says to add a 'slip additive" if you have a QD. How do you know if you have that? I have the 3.7 v6 loredo AWD. I have also been reading 2 quarts is about what you need to refill (I am planning on just pumping out old fluid) Do you just fill until the fluid starts coming out fill hole? Lastly what fluid do you recommend?

Sorry its so long, just my first time doing it and I dont want to screw anything up! thanks in advance guys!

PS: I know taking the diff. cover off is the proper way, but that seems a bit cumbersome for my 1st fluid change....

Re: Differentials
you dont need the additive. slowly fill until it leaks out and i use mobil 1

Re: Differentials
Awesome, thanks. Will it hurt anything to not do front/rear at the same time?

Re: Differentials
nope, it is easier to do them together though. you do not even need to jack up the jeep for the rear.

Re: Differentials
The first time I did mine I used the dealers ATF-4, but I will be trying Royal Purple Max on my next change, a little bit on the high price but its once every several thousand miles, so its not really a biggie.....

Re: Differentials

i have the NV245 so i have to use fluid from the dealer. check what case you have and see what fluid you need. do not use anything other than what is recommended

Re: Differentials
Most of the debris and particles will be laying in the lower area of the diff, so when you just remove the fluid with a pump, you will keep the dirty part in and mix it again with the fresh fluid. You should better take a little bit more time and remove the covers and clean it out well.
Ofcourse its your Jeep, but if you plan to keep it for a while, i wouldn´t take the risk.
And regarding this:
Will it hurt anything to not do front/rear at the same time?
At the contrary, it will probably safe you some pain in the back when you don´t do both at the same time.:lol:

Re: Differentials
The front diff has drain and fill plugs.also the cover has 1 of the mounts mounted to it, so you don't pull the front cover. Drive it around to warm it up before you drain it.this will help get the crud out as it won't be settled to the bottom.
