4x4 hub question

[abeauvais]

So the bearings are going on the front end of my 2000 ford ranger 4x4. I just order new hubs/w bearing but I am not sure if I got the right parts. This is what I ordered from rock auto http://www.rockauto.com/catalog/moreinfo.php?pk=4287453&cc=1362798

I guess I really wanted to know if those will work and how can I tell if I have hubs with pulse vacuum or not. I already know I don't have 4 wheel ABS. Any input would be great!

Remove the center cap covering the lugnuts.
If you see a 32mm nut in the center, you DO NOT have PVH hubs, you have live axle.

The link you posted is a live axle bearing.
All 2000 4wd had 4WABS. You can tell because the hub(s) you are about to replace has a speed sensor.
