Do you work for Warn or something ?

The old S-10 had a center disconnect system. Vacuum operated sleeve locked right axleshaft to the diff. There are no hubs as such, they're always rotating. I have an S-10 in the driveway.

If the stock X hubs are made by Warn, what's the number for them ?

Whay are studs better than bolts ? Why don't they back out or loosen ?

Since you seem to be a fountain of information please explain.

Thanks.
