OK, I'll do that on the other one then. Too late for the knuckle I have on already. I have a few more questions tho~
1) Do I pack the everything completely full of grease? I thought I read somewhere that certain parts\areas should only be coated, otherwise the drag reading would be off?

2) I think I threw away one of those metal rings that go on the back of the knuckle, under the rubber wiper. Are those hard to replace? Do I really need it?

3) When I bought the truck, I had some chromo axles\birfs installed, when I took them out, they came out one at time, the birfs are not clipped or whatever it is to the axles. Is that a problem? Will the axle slide out of the birf and too far into the diff?
