Caution Red LocTite is perminate!
You will need to shake the wheels up & down, and right to left.
This will help you determine if the problem is a bearing, ball joints, tie-rod end, or the rack. If you are going to use RTV, there must be no oil! It will not setup if it is contaminated with oil before it cures.
This is not the type of job you will want to do twice!
