WHEELS, RIMS AND TIRES
Before mounting wheel assemblies on
vehicles, be sure all parts are clean and
free from foreign matter. Excess paint on
wheel stud hole perimeters can permit
wheel mounting nuts to loosen with use.
Be certain wheel bolt threads are clean to
allow correct torquing of nuts. Do not apply
any lubricant on threads.

Wheels or hubs, bearing cups, nuts, locks, hub caps,
shafts and spindles are to be free from any foreign
matter. Bearing cones must be packed with specified

Front and Rear Axle Adjusting Nut
After wheel hub and bearings are assembled on the
spindle or axle tube, tighten the bearing adjusting nut to
68 Nm (50 ft. lbs.) while rotating the wheel and hub
assembly. Then back off adjusting nut 1/4 turn. If
adjusting, lock or cotter key can be installed at this point,
do so. If not, tighten nut to nearest locking position and
insert lock or pin. Refer to Cotter Key Installation. On
front axles which use locks without pierced lock washer,
bend lock over adjusting nut.
