Getting ready to put my new '08 diff cover on this evening and I have a dumb question?? Can Anyone confirm that the fill port for the Dif housing is on the front/ left /lower part of the housing? I know the housing is supposed to hold almost 7 pints. and this looks awful low on the housing to hold that much fluid??

I told you it was a dumb question but I had to ask...

I did my cover a short while ago and yes that is the plug. It will take all 7 pints to fill ,don't forget friction modifier if you have ls. 3/8 ratchet is all you need to take out the plug.

 

be sure to remove all the metal shavings from the plug too...

 

Don't know about your diff, but all the ones I ever played with had a plug with a square 3/8 socket in it. So use your 3/8 ratchet and unscrew it. Some plugs are the male version, ie square peg instead of square hole.

Some of these plugs are in there really tight and a cheap ratchet or extention may twist off, I have done this before. All the ones I have seen are right hand thread.

Not many other plug like things on a differential so unlikely to goof. I could be wrong tho.

The fluid should be either a half inch down or more usually level with the hole. Regular diff lube stinks. Other lube is just ATF and red and thin.

Good Luck,
