Word of caution and this was probably a contributing factor was I did not clean the hub surface. Sand any rust or crud on the hub off so that it will get a good clean surface to seat on.
Cleaning the hub surface. How much cleaning is necessary? I was thinking of just wiping them down with some acetone or brake cleaner and scraping off any gunk and then Red loc titing them on there and torqueing to at least 90 ft-lbs. How's that sound?
Sand it back to clean steel. Any chunks of rust will cause it not to make a tight seat. This is a basic rule on any new wheels as well. The hub must the clean and free of rust and anything that would prevent a good full contact with the rim/spacer. I used a disc sander on a drill when I did my disc brake conversion and needed to install the new rotors. took all of 2 minutes with the studs out.
