Front Diff Oil Change

Justintoxicated · 10-16-2006, 07:13 PM

I have almsot 25k on my titan, but have done very little in 4x4.

Is it time to change my front Diff Oil?

Anything else I should be doing at this point?

Transfer Case etc?

Definitely front diff & transfer case. Those are cheap & easy. I would have the dealer flush the tranny, but I am compulsive. You didn't mention rear diff, so I assume that was done recently.

Well I'm not sure how to go about doing the front diff very easily, I have a tool I may be able to use as a pump (for bleeding brakes and vacume testing lines) not really sure if it would work but I can have the dealer do it with my oil (amsoil) I suppose. Can I do the transfer case myself (no idea what oil it takes) ? Tranny flush already ???

Screw the rear diff I'm getting a new one (but I re-filled it at 7k or so anyways)

You can do the diffs & transfer case yourself. You don't really need a pump, although you can buy one for a few bucks at an auto parts store. The transfer case spec is Nissan Matic D (not gear oil like the diff & not Nissan Matic J like the tranny). My thought is that, unlike the tranny, you may be able to use something other than Matic D for the transfer case. I will leave it to others to recommend exactly what else you might use.

Front Differential: Mobil 1 75-90W
Transfer Case: Mobil 1 ATF
Rear Differential: Mobil 1 75-140W

Hint: When draining the Transfer Case, place the drain pan WAY behind the drain hole, as it will "spew" out and over the pan......DOHHHH.

I'm more concerned with filling the front differential on my 4x4, diff fluid is pretty think and I'm not sure how I will be able to fill it using a funnel (rear you actualy have a place to raise the funnel above the diff....)

I have never changed the transfer case, how do I do it?

Sounds like I need a new larger oil pan, all I have is a small dinky one... Once again not having a garage is an issue...

Just drain and fill for the transfer case. It's even easier then changing your oil. Haven't done the front yet but I used Royal Purple and put a piece of tubing on top and just squeezed the oil in. Worked pretty slick.

I have an oil filter with a tube/hose will that work for the front? I still can't see an easy way to do this, plus I don't have a good jack or anything like that....

The royal purple stuff has a pointy tip on the bottle where you can slide 1/4" (i think) tubing over it. Run the tubing up to where you fill the diff and start squeezing. Or you can just run down to napa and get a little pump...I'm just cheap.

I was just digging and I'm certqinly glad I made this post. I wasn't sure when I had changed my Transfer case oil and front diff previously, but because I posted this I'm certain it was around 25k

My service manual I was keeping track of all my maintanence in was stolen.
