How to replace Tail housing bushing without a press or without destroying the tail shaft?

Got a vibration in my driveline somewhere and everyone is saying to replace the tail shaft bushing.

EDIT: Im not sure what transmission is in there I think its a TH350.

Pull the extension housing and run it by a transmission shop. Spend a few bucks and save yourself some aggravation.

I have never pulled a tailshaft apart. What should I expect when I pull it apart?

Remove the driveshaft (exercise all due safety measures).
Remove the four bolts on the tailshaft housing (extension housing).
Place a drip pan under it, and tap the sides of ghe housing with a soft mallet to rock it off. Replace the o-ring and rear seal after they install your new bushing.

How much fluid will I lose?
And what O Ring?

And what should I use for a sealant when I put it back to together?

If you raise the rear high enough to work, with the front in the ground, you may not lose any. You will see the o-ring when you separate the extension housing. No sealant is required. The new rear seal should be self sealing.

What about in between the extension housing and the rest of the transmission?

That's where the o-ring is. It's about 4" in diameter.
