• 163-203 N-m (120-150 ft. lbs.) on 8 stud single
wheel
(14) Apply brakes several times to reseat brake-
shoes and caliper piston. Do not move vehicle until
firm brake pedal is obtained.
WHEEL BEARING REPLACEMENT
On models with tapered roller style front wheel
bearings, the bearings and races can be serviced sep­
arately when necessary.
The bearing races do not require special tools for
removal. Either race can be removed with a long ta­
pered brass drift punch.
On models with unit style wheel bearings (Fig. 41),
the rotor, hub and bearing assembly are all pressed
together. However, i t is only necessary to drive out
the wheel studs with a copper mallet, i n order to sep­
arate the rotor, bearing and hub for replacement pur­
poses (Fig. 44).

Bearing)
WHEEL NUT TIGHTENING
The wheel attaching nuts should be properly tight­
ened to ensure efficient brake operation. Overtighten­
ing the nuts or tightening them i n the wrong
sequence could cause distortion of the brake rotors
and drums.
Impact wrenches are not the best tools for tighten­
ing wheel nuts. A torque wrench should be used for
this purpose at all times.
The correct tightening sequence is important i n
avoiding rotor and drum distortion. The correct se­
quence is i n a diagonal crossing pattern as shown
(Figs 45 and 46).
Seat the wheel and install the wheel nuts finger
tight. Tighten the nuts in recommended sequence to
1/2 required torque. Then repeat the tightening se­
quence to final specified torque.
Wheel lug nut torques are:
• 108-150 N-m (80-110 ft. lbs.) on 5 stud wheel
• 163-203 N-m (120-150 ft. lbs.) on 8 stud single
wheel
• 176-217 N-m (130-160 ft. lbs.) on 8 stud dual
wheels
