FRONT WHEEL HUB AND KNUCKLE
4. Use a drift and a press to install wheel hub.
5. As shown in the figure, apply a load of 49030 N (5000 kg,11,025
lb). Rotate in forward and reverse directions 10 times each to
ensure a good fit.
6. At a rotation speed of 8 - 12 rpm, place a spring balance at the point where strut is joined (upper-side bolt
hole). Measure rotation torque. Refer toFAX-17, "
Wheel Bearing".
NOTE:
If a load of 49030 N (5000 kg,11,025 lb) cannot be applied, carry out the following actions.
lAssemble drive shaft and tighten wheel hub lock nuts to specified torque. Then rotate in forward and
reverse direction 10 times each to ensure a good fit.
lAt a rotation speed of 8 - 12 rpm, place a spring balance on hub bolt to measure torque.

Rotation torque : 1.645 N·m (0.168 kg-m,15 in-lb) or less
Spring balance reading : 10.6 N (1.1 kg, 2.4 lb) or less
Rotation torque : 2.125 N·m (0.217 kg-m,19 in-lb) or less
