yoke change 489 case w/o disassembling

just found this in the I Net.... ( but i think i will use a mix of yours above and this. I definitly don't use what i wanted to use and overtight )

1. check the yoke for the backlash before you take it apart
you can get a good feel for it by rotating back and forth softly .
kind like rocking it.
IF back lash is tight then proceed to next step if loose like more than tight wiggle .
than the rear needs inspection.

2. with a bright light and a pick or finger nail count the threads protruding the pinion nut ( i Change yokes so i must be sure they have 100% the same measurements )

3. record that thread count .

4. zip the nut off with impact gun while holding yoke with your free hand .

5. change seal .

6. clean rust off the threads and put 1-2 drops of red lock tight on the nut threads .
tighten to 175 foot pounds no more ,no less while holding the yoke solid with a pinion holding tool you can make one out of long piece of flat stock so it locks against the frame or ground while you toque the nut.

7. Count the threads if same leave it alone.
less tighten 1/8 turn until same threads show the key is to not over tighten.
If any one who has rebuilt axles knows it takes over 200 ftlbs to start to crush the collar.
IF this is done right no problems will come of it.
