This part, through which one of the axles passes into the trans-axle leaks gear oil through the threads. No problem with the axle seal on the inside of the part, which I replaced last year. But when I had it out to replace the seal, I did not replace the o-ring seal on the outside.  I'm assuming this is the reason for the leak.  Would someone please help me with the name or part number of that seal?

 

Thank you!

You can coat the threads with "the Right Stuff" rtv.

 

it won't leak after that unless you remove or adjust it again.

Thanks to both of you for the information!
