Okay,
So after many searches, and even 1 deleted new topic. The seal at the end of my enclosed drive shaft leaks. I want to change it. From what I gather so far the best way is to drop that section of shaft and move it to the bench. then looking side the shaft look for the two bronze bushings and a "seal" I need to check to see if they are pinned in from the outside. if they are pinned carefully drill out the pins and then in some safe manner(meaning no damage to inside of shaft housing) remove two bushings and the old seal.

Once this done and I have taken a short break;
I am not sure which bushing replacement to purchase- chev's of the 40's has a one piece with seal that I am leaning to.

So the shaft housing is empty. I begin by putting a small amount of assembly lube and then tap this into place- Is there an exact measurement of how far to insert it?
Than I re-Pin the bushing with the next item

So do I lube the seal, putting the cupped side facing the trans in front of the bushing as I tap it in?

I understand how it supports the u-joint and shaft, and how the seal works, but I do not have the parts in front of me and I kind of need to to understand how it goes together.

Thanks all for the help.
