CAUTION
• Remove rust and dirt from a wheel stud and nut, lightly lubricate the threads
with engine oil, gear oil or power steering fluid and turn the nut on the stud. If
the nut does not turn smoothly, the threads are defective.
• If the threads are defective, replace both wheel stud and wheel nut as a set.
• If any wheel stud is broken, change all the wheel studs and wheel nuts on the
wheel.

SERVICE AND MAINTENANCE
3. Remove rust, dust and mud from the
fitting surface, hub fitting surface or
wheel-to-wheel mating surfaces, and
wheel nut seating surfaces (tapered
surfaces) of the disc wheel, and from
the threads of the wheel studs and
nuts.
CAUTION
• Clean the disc wheel to remove dirt
and rust from its fitting surfaces,
hub fitting surface or wheel-to-
wheel mating surface. Also clean
the tapered portion of each nut. If
you fasten the wheel nuts without
removing dirt and rust, the wheel
nuts would later loosen and the
wheel might be detached from the
vehicle while driving. This could be
very dangerous.
4. Install the wheel while aligning the
stud holes in the disc wheel with the
wheel studs.
When installing the rear wheel, place
the outer wheel so that its tyre air
valve will be 180 degrees apart from
that of the inner wheel to enable
inflating both inner and outer tyres.
