So I'm going to swap out the bearings as well. Inner and outer pinnion and diff bearings. So do I need to buy the "cups" as well? I think Ford calls them "races".

Check out this schematic:

What all in there do I need? I assume I do have to buy the cups as well because they have different numbers on them. So I assume I want #6,7,16,17,18,19 and 20. I guess with 78k miles it would be silly to change the ring and pinnion without at least changing the inner and outer bearings.

My biggest concern is about these damn things being quiet. My 3.73's howled like hell after Mr. hack job mechanic ****d 'em all up. (Got it right the second time around.) All the necessary tools are available, so hopefully we can do this thing right.

if you buy a "install kit you will get shims, nut, collar, and both the cone and cup of the brgs for a whole lot less money.
i purchased a table top bearing press from bumper to bumper when i did mine. i found the gears ran the quietest (spelling?) with the contact pattern favoring the inner part of the ring closer to the inner edge). however i pefer a more centered pattern and the gears became slightly noisy. the pattern location is mostly controlled by pinion shim thickness (that is why you you neeed a brg press) backlash is mostly controlled by moving the carrier left or right.
this is not the ultimate info, just what i found, bobn
