FRONT AXLE HUB ASSEMBLY]]C[[ HUB ROTATION STARTING TORQUE CHECK
1. Set special tools MB991000, MB991017 and MB991099 as shown in the figure, tighten the nut to the specified torque, and press-fit the hub into the knuckle.
Tightening torque: 144 - 176 Nm (107 - 129 ft-lb)
2. Rotate the hub to make the bearing well-greased.
3. Use Special tools MB990326, MB990685 to measure the hub rotation starting torque.
Limit: 1.5 Nm (13 in-lb)
4. Hub rotation starting torque should be within the limit value, and there should be no roughness and gritty feeling in rotation.
]]D[[ WHEEL BEARING END PLAY CHECK
1. Use special tools MB991000 and MB991017 to measure to determine whether the wheel bearing end play is within the specified limit or not.
Limit: 0.05 mm(0.002 inch)
2. If the end play is not within the limit range while the nut is tightened to the specified torque, the bearing, hub and/or knuckle have probably not been installed correctly. Replace the bearing and re-install.
Tightening torque: 144 - 176 Nm (107 - 129 ft-lb)
