6. WHEEL STUDS
Stripped threads may be the result of excessive
torque or may have been damaged during wheel
installation when placing the wheel over the
studs. A stud having damaged threads must be
replaced. Broken studs are a direct result of
operating with loose stud nuts or improperly
seated wheels. When a broken stud is replaced,
the adjacent studs, on each side of the broken
one must also be replaced since they could
have been subjected to excessive strain and
may be fatigued.
When installing wheel studs to hubs, check nuts
retaining the wheel stud to wheel hub and
replace if they are deformed, damaged or
severely corroded. Install nut (and washer where
applicable) to new stud.
