Difference between A Twelve-Point Bolt with Ribs and A Twelve-Point Bolt without Ribs
The contact surfaces -arrow A- and -arrow B- are different on the two-point bolts.
Caution
The wheel bearing must not be under load when the drive axle threaded connection on the wheel side is loose.
If the wheel bearings are under the load of the vehicle weight, the wheel bearing will be damaged. This reduces the service life of the wheel bearings.
The drive axle bolt may be loosened maximum 90º when the vehicle is standing on its wheels.
Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If a vehicle must be moved, be sure to note the following:
