WHEELS, RIMS, TIRES
Worn Wheel Stud Holes
This condition will usually be accompanied by evidence
of a bright worn surface on the wheel face, indicating that
loose wheels are working against each other. The wheels
should be replaced, Fig. 4.
Worn Hub Face
A worn hub face is always caused by running wheel
assemblies in a loose condition. If the wear is not too
excessive the hub face can be machined to a flat surface with
the studs removed, otherwise a new hub should be installed,
Broken Or Cracked Hub
If the hub barrel or flange is broken or cracked the unit
must be replaced, Fig. 6.
Broken Or Damaged Studs
Stripped threads may be due to excessive torquing of
the studs or when the wheel is placed over the studs, Fig. 7.
