This is not meant to be a step-by-step how to do it thread, it's more meant as a place to discuss the correct (?best) method to install U-joints including the methods/procedures to center the U joints in the yolks and adjust axial play.
There's plenty of videos on you-tubby showing people replacing U-joints although most seem to rely on a BFH and not much technical skill.
Background:
Anyone who has replaced U-joints on their 80 Series with a new Toyota part knows when they opened up the Toyota box (Spider Kit) there's a small instruction sheet included and that sheet states to check for axial play to ensure it doesn't exceed 0.002". And if there's too much play to use different thickness snap rings (2.00mm, 2.03mm, 2.06mm, 2.09mm) to adjust the play.
Long Story:
In the middle of rebuilding the rear driveshaft on my 97 FZJ80 with ~250,000 miles on the vehicle. This was started only as a PM as I had the driveshaft out, but felt slight notchiness on one joint/yolk so decided to go ahead and rebuild/service the whole driveshaft. I wasn't getting any vibration however from that shaft.
It's going to take me awhile to load up photos (I'm not finished with the job yet due to weather) so in the meantime I'll post up the link to a very good series of instructional videos done by an instructor at Weber State University Automotive Tech Dept. Some of these are long videos but the instructor goes step-by-step and by the book, seems obvious this guy knows his stuff.
What is most apparent is the vast difference in how this instructor goes about it (takes longer to do of course because he's explaining everything to the "students" compared to how most people just take a BFH (or vise), pound/press in the bearing caps, slide in the snap rings included in the kit, hit the yolks with a hammer a few times, and consider it done.
So which is the best (correct) method to install U-joints?? That is the question (watch the videos first).
And part of that process: how to best center the joints and remove Axial play.
This initial link is to the first video of a seven part series (each successive part pops up in a window when video is completed). When you've finished watching them all and pass the written exam (closed book) you'll get a Certificate in the mail along with a coupon good for a 30 pack of Lite beer to do with whatever you're pretty little heart desires

IMHO this is an excellent video series on the topic.
Watch all the videos but here's Part 6 discussing installing the U-joints into the yolks:
And next is Part 7 discussing Centering and setting up Axial play to spec:
