To Grease Or Not To Grease

[esff32]

As i have gone through the build process, I often second guess whether or not I did something right or not. This may be a series of dumb questions so please bear with me.

Was I supposed to put grease on the spindle shaft before I pushed on the hub? If so, what type of grease should i use and are my spindle hub nuts no good, due to the fact I already torqued them down? I also noticed that there is quite a bit of drag on the hub when it is torqued, is this normal?

I also have had a hard time getting my torque wrench on the ball joint castle nuts, any solutions? I have noticed that the hole for the cotter pin is well above the notches in the nut when torqued down, is this a problem? Any tricks on how to prevent the spindle from spinning around while torquing?

Any help would greatly be appreciated. Thanks guys.
