Default Looking for a part number

Good day,

It seems I can not describe to the "dealer" what part I need ...good enough. And I do not have access to "diagrams" at this time.

Anyone know the part number for the O-ring seal that seats between the Diff Housing and the transmission?

The dealer keeps quoting me the seat that is around the output shaft into the Diff (#24228816) and that's not what I'm looking for

Thanks!
Michael

The big Oring between the diff/tranny. I got a small leak of stinky feet fluid

Try #12458151 which number has been superceded by # 89047954. That is for '97 - '02 don't know what year you have.

Thanks!

well...my chassis is a 97.

But my diff and tranny exploded within a week of each other. So its a T56 with a C5 Diff housing. Inerds are well... not stock

I think the when it was all assembled, the O ring was damaged.

I thought all the C5 stuff was all the same...well at least this portion.
