INSPECTION OF HUB ROTATION STARTING TORQUE AND WHEEL BEARING LOOSENESS |
|
1.Install the following special tools to the hub and tighten to the specified torque.
2.Fix the hub in a vice using a piece of wood or the like. 3.Rotate the hub to make the bearing well-greased. |
) |
4.Use special tool preload socket (MB990326) to measure the hub rotation starting torque. Limit : 1.4 N·m 5.If the hub rotation starting torque at the specified tightening torque (160 ± 16 N·m) exceeds the limit, replace the hub. If there are rough or gritty feelings in rotation, replace the hub. |

6.Set a dial gauge, and move the hub in the axial direction to measure the looseness in
the wheel bearing. Limit : 0.05 mm 7.If the wheel bearing looseness at the specified tightening torque (160 ± 16 N·m) exceeds the limit, replace the hub. |
