Cool, thanks for the info, Mark. Our VXes are the same age...that's so cute. :p :laughing:

I had my diffs done right before I left Chicago, so its time.

Quantities have been posted many times before and are also listing in your owners manual - please try the search function.

Approx amounts are as follows:
Tranny flush - at least 10 qts Dexron III
Tranny filter or drain - 4 qts Dexron III
TOD/Transfer - 2qts Dexron III
Front diff - 1.5qts
Rear diff - 2qts
75/140 in both is fine in Texas unless we have a cold winter

Can't change any fluids too often - see manual for time/mileage periods

@ 30K you also should be having your wheel bearings repacked....

Hope this helps.

Peace.

I would also add that we can use the ATF fluid for our power steering fluid.
So when getting a case - get a bit more to flush the power steering juice.

And-
Probably doesn't affect you, in your temperature zone - but the manual has different viscosities for fluid for front and back diffs. Others should check their local low temp for proper selection.

I did all my fluids myself last year. Pretty painless. Maybe I can do a how to for all if needed....

Some Data sheets:

and another list..

might help some people.

Apparently Amsoil has been "synthetic" since like 1920 (it's a corn based lubricant) and it's supposed to last forever. Well, not really, but Amsoil states that the transmission fluid is good for 500,000 miles. They also state that their oil is good for 25,000 miles between changes. There are some additives that you have to pour in every now and then, but that's about it. I didn't do the oil because I just don't trust a 25,000 mile oil yet.

Anyway, all of that is to say that when they where changing the fluids out they said that the old stuff was in fantastic shape and could have gone another 70,000 miles (the VX just turned 70k after Moab). To my knowledge those fluids where never changed by the previous owner so it seems like Isuzu put some good stuff in there to begin with.

I'm completely in agreementalness with Mark...I have run nothing but Amsoil in every orfice since about 20k, & I think my oil usage during the Moab excursion (1 qt. in almost 2500 mi.) speaks for itself.

It's more expen$ive to use @ regular change intervals, & there's no WAY I'd go 25k on an oil change...but there's nothing too good for Suzy.:thumbup:

IMO, it's the "good stuff".

If you do any water crossings you will want to change your diff fluid more often as water can get in through the breathers (unless you have extended them to higher ground).

Kenny,
Thank you for posting those!
I never had a manual, and those specs will also (hopefully) help sell my '99.
Thanks again!

Yes, thanks Kenny. I know I have all this info in the manual, but you just made it nice and easy. I think I am going to go buy some fluids today and try to get the diffs dones this weekend.

Timing Belt change interval.

I notice in the above post #17, the timing belt change interval is 100,000 miles. Would that also apply to the JDM 3.2L engine??
I believe our 3.2L engines are dual overhead cams - aren't they??
The single overhead cam 3.2L engine used in most Rodeos and Jackeroos in Australia requires changing at 100,000 KM (62,000miles).

I have just ticked over 104,000 KM and want to be safe.

Appreciate your input guys.

Front diff ports, which is which?

I don't like doing things unless I am 100% sure.

Can someone point out which is the drain and which is the fill? I assume the big plug that is high up is the fill port. Now, according to Dub's earlier post, the lowest bolt should be the drain, so which one is it exactly?

Fill???

Drain???

In the above photo you can clearly see the dripping problem I have also. I think Jharris might be right about it being the seal there. The manual mentions this as a potential problem.

It's hard to tell from this angle, but I think it's this one...

In any event, it's the one closest to the ground.:_wrench:

And you are correct in your assumtion that the upper ones are the fill/level check holes.

You're the best, Dub. I figured that was it, but with your red circle, now I am certain.

One more thing, does anyone know the size of the socket needed for the diffs? I need to get one I think.

:_wrench: Don't know the size, but you could give it a shot with a large crescent wrench. Snug it up tight & give it a few persuasive gestures with the heel of your palm...:_wrench:...:thumbup:

Worst case scenario, you bloody up some knuckles, learn new swear words, & have to clean up the head of the plug with a file...so a socket will fit.:smilewink

hmm i forget the size.. i want to say the rear is 24mm.. but it could also be 25 :_confused

word to the wise... take the fill plug off first... its unfortunate to get the fluid drained out only to realize you cant get the fill plug off

Good tip, Etl, thanks. I was going to do everything yesterday, but I just didn't get to it. :( Next week hopefully.
