Rear Axle oil change

[1996MGM]

Hi All,

I want to change the rear axle oil on my 1996 MGM.

Does anyone know a tech article or a 'how to' article on this subject?

TIA,

I usually drop the rear cover (make sure you have a new gasket) and let the fluid drip out.

If you have a rear end with a traction lock, you will need to add an additive with friction modifiers. I am not sure what 8.8s use for gear oil, either. But once you do all that, put the cover back on with the new gasket. There is a plug on the fornt case of the diff case. Remove it with a ratchet and extension (3/8 drive, i think) And fill on level ground until the fluid level is about 1/2" (12mm) from the bottom of the hole (use your finger)

Then reintall the plug, and happy hotrodding!

90 weight will work fine. I don't ever bother to change it unless I have the cover off anyway. 200k+ on my gear oil.

I second that, I didn't use a gasket on mine. Just silicone. A good trick is to lay good solid bead of the suff and put on the cover, but don't put it on all the way. Then after about 5or so minuts put it the rest the way on. This gives the silicone some time to cure a little, so when you snug it up, you get a better seal. It should be fine either way though. If you need pics I have plenty, I just rebuilt mine.

It's a good idea to remove the fill plug BEFORE removing the rear cover. Those plugs and be a real biatch to remove. Nothing worse than finding out you can't get the fill plug out AFTER you've emptied the axle!

I saw the pictures.
Wow, they are breathtaking!

I have this instant gasket (used it for the overhaul of a Suzuki motorcycle engine).

Can I also use it for the cover of the rear axle diff?

I would get the silicone rubber (Ford - D6AZ-19562-AA Motorcraft - TA-32)

Other than that I would get some Ultra Copper.

That is almost the same thing I used, except mine isn't High Temp. That will be fine man.

I read the tag on the diff of my car.

Can someone explain the secret message on the tag.
