Front & Real Differential Fluids

[Dare2Dream]

Is there a need to use anything to reseal the drain hole? What do you guys use?

[Ascinder]

I never use anything to reseal the fill or drain, but you could use some silicone gasket maker like permatex ultrablack. It's high temp and largely impervious to almost all automotive fluids. Mine have never leaked or seeped, so if yours does, check for it being cross threaded, and also check the part of the plugs seating surface for knicks or burrs.

OK, I am right in the middle of doing this right now, and looking at the rear diff capacities Kenny posted earlier, it says 2.3 quarts on list and 3.2 quarts on the other?????????????

WHICH ONE IS IT???? Also, does anyone know the torque specs for the drain and fill holes?

Thanks - Bart

Oil change: w/filter 4.3 qt. (4.0L)
Automatic trans: 9.1 qt. (8.6L)
Transfer case: 2.0 qt. (1.9L)
Front differential: 1.5 qt. (1.4L)
Rear differential: 3.2 qt. (3.0L)
Fuel tank: 22.5 gal. (85L)
Cooling system: 7.4 qt. (7.1L)
Refrigerant: R134a, 1.43 lb. (650g)
Compressor: PAG, 3.0 oz. (90cc)

OK well, one list says 3.2, and one says 2.3, that is why I am confused. Furthermore, I put in roughly 2 quarts and then it started to dribble out. Is that enough? Or do I need to get another quart in there????

Thanks,

Once it dribbles out, it's full. It would be a good idea to check it in a couple of days, just to make sure.

Hi the diff plugs should have a thin copper ring the same as the transfer and gear box have - in adddition i wouldn't leave the timing belt for the 100,000 miles that Isuzu recommend - 100,000 km maybe but not miles

Thanks Steve, I thought that little question had passed over everyones head.
Looks like I am up for a timing belt and tensioner change then. Another weekend with the Mrs nagging that I don't do anything for her.
Oh well - amazing how my hearing deteriorates after a few beers.

just curious.. when checking the fluid in the rear diff.. i take the filler plug out and there is a pressure release - hissing like opening a bottle of soda for the first time.. level seems fine, it dribbles out once the plug is removed completely.. dont have any issues with it.. just something that strikes me as odd as i dont see any reason there should be pressure buildup in the diff

anyone else experience this?

Eric,

I know the front pumpkin has a breather tube on the driver's side. I've never looked for one on the rear. If there is one and your's is clogged, that could cause the pressure differential.

I use Royal Purple in Front/Rear ends, and Dexron IV in Tranny & transfer case. It's a synthetic, but good for Dexron III trans. Also blend my own Mobil 1 /Mobil (3qt/2qt) for engine. I'm a big believer in synthetics, working in the aerospace industry and many years racing and track experience.

Yes,i think the differentials got breating tube,they looks like rubber straws.

They aim upward,i don't know if they are removable so you can clean them

[psychos2]

1 tip for when you change fluids in anything that has a drain and a fill plug, ALWAYS REMOVE THE FILL PLUG FIRST. If you remove the drain plug and cannot get the fill plug loose you are stuck and cannot get the fluids back in. And I believe it is the 2.3 qts not 3.2 qts for the rear diff. shawn

[psychos2]

Just looked it up 2.3 rear and 1.5 front. shawn

Actually the rear diff do have one,it's very short though;About 10/11" long.
