1) Flat level surface, chock the front tires.
2) Jack the rear up just until the tires clear.
USE jack stands. (DO NOT EVER just depend on a jack)
3) Remove the rear bolts holding the rear U-joint in.
Carefully use a tool to pry one of the U-joint cups, until the U-joint comes loose. DO NOT drop the cups off. Keep one hand wrapped around the cups as you pry the U-joint loose.
When U-joint is removed, suggest use black plastic electrical tape, and tape across the two cups, so they do not drop off.
[GOOD time to see if they are dry, and the U-joint is in good condition. DO NOT loose needle bearings ]
4) Remove the bolts that hold the Carrier Bearing Support to frame.
(Put the nuts back on a few threads of the bolts, after putting them back through the holes, in the Carrier Bearing Support strap. This way you won\'t lose them)
Lay the Support strap, and rubber aside.
5) Slide the driveshaft out of the back of the tranny. (Transmission)
It would be a real good idea to go to an auto parts store first, and rent a plug tool for the back of the tranny, once you remove the driveshaft. Keeps the tranny fluid from leaking out. Manual or automatic. (It is plastic, and a cheap rental)
The rear half-driveshaft slips out of the front one.
BEFORE removing make a mark on the front half-driveshaft, and a matching mark on the rear half-driveshaft. The driveshaft is a Balanced unit. Should be put back together the same way, it was taken apart.
Take the driveshaft with the carrier bearing on it to a shop, so they can press the old one off, and the new one on.
Reverse your steps.
