How to Keep Your
Wheels Rolling Strong
Regardless of how "cutting edge" your wheels are, you'll still
need to keep an eye on them for signs of damage. An ignored crack between
tow bolt holes, for example, can turn into a dangerous and potentially fatal
accident. Regular upkeep can eliminate larger problems before they occur.
Gunite Corporation, has developed the following set of guidelines to watch for
when conducting wheel and hub inspections:
FOREIGN MATTER ON/AROUND HUBS
Corrosion can not only hinder hub support, it can also be a signal to
more serious problems within wheel end assembly. Use a wire brush to clean
the hub's machined surfaces, stud threads and ball seats.
WORN STUD HOLES
Caused by studs turning in their respective holes, this condition is
caused by insufficient torque on the back nut. The hub needs to be
WORN OR DAMAGED MOUNTING FACE
A loose wheel assembly or an improperly installed outboard mounted drum
is the culprit. This also calls for hub replacement. To avoid this
problem, follow proper torquing procedures.
BENT HUB FACE
When wheels run loose for an extended period, the hub face is inevitable
damaged. A common symptom is wheel nuts that are constantly in need of
re-tightening. The only solution to this problem is replacement.
Cracks that run between bolt holes, hand holes, or center holes can be
extremely dangerous. This is often caused by loose wheel nuts, improper
torque, damaged hub mounting surface, loose/broken studs or a worn stud groove.
A cracked wheel is a dangerous wheel, and must be replaced.
Loose cap nuts are a common cause of this condition. The entire assembly should be checked for damage if you notice the appearance of these
streaks from the bolt holes.
SEIZED, BROKEN, OR CRACKED FLANGE NUTS
Corrosion, excessive torque, and insufficient nut strength are some of
the reasons why a nut may fail. When a nut is added, be certain to
lubricate it properly and follow proper torquing procedures.
Often the result of loose cap nuts or overloading, it requires the
replacement of BOTH the broken stud and the stud on either side of it. If
more than one broken stud is found, they should all be replaced.
Excessive torque will strip the threads on your studs. When
replacing the stripped stud, make certain to follow the recommended torquing
