[modern] What size is this thing

Hey all you kitty lovers,

What size is the plug on the differential. I wanted to change the fluid
and nobody has anything that will fit. Also, I was going to use Castrol
Syntec, is that the best to use??

Thanks,

Hi Kenneth,

It’s supposed to be 1/2 in. And if there is nothing wrong with the plug, a 15
mm 12-point socket should work nicely.

However, I think you got one like mine, this has happened before, and not
just to me! My theory is that there was a batch of defective plugs on some of
the '90s. I lay underneath that big car trying one wrench after another and
nothing fit! Problem is, that plug is rectangular! Thing to do here is to use
a 1/2 in. open-end wrench that fits across one dimension and hold on to the
other end of that wrench with an adjustable wrench so you can get the &%$^*@
thing off. Do it gently so you don’t break the wrench. When you get the plug
out, file it down so that it is 1/2 in. in both directions. Some people have
altered the wrench instead to make it fit, but why wreck a good wrench for a
job you only have to do once in a blue moon?

Ken,
For the drain plug, on my car I use a 5/8 inch 12 point socket I think.
It has to be a 12 point socket though.
For the fill plug, you use a 1/2 inch extension.
I go in through the trunk…there is a bung that lines up(almost) with
the fill plug.
Warm the lube up first, as its a lot easier to squeeze it into
the differential.
I use a piece of hose, and lots of rags, and I remove the rug
from the trunk, as I always spill some.

In the summer I use the most expensive 85w 140 I can find,
and in the winter I use the 80w 90.
It must be working because I have only needed 2 new differentials
in 3 years!
