generally the spindle nut needs replacing when you remove the nut. the new nut has a nylon locking ring on it, that is only designed to stay tight one time. once this is removed the nut will not stay tight with a second application The nut is a torque to yield design. After reaching torque specs, the threads have stretched. Reusing the nut will allow the nut to back off, since you can't properly torque it but one time.
