Q1: Did you check all bolts?
Q2: Did you have the tire up there before everything was tightened down?

I know a few people with the 2" brackets on the full size rack with no issues.

Was this rack used or bought new? If it was bought used, do you know what year truck they had? I'm trying to determine how old the rack is.

There have been minor changes over the years.
