Frequently Asked Questions

Yes. The nut should be torqued to the specifications found in the vehicle's service manual.

Yes. It is normal for the bearing to have some movement inside the hub assembly; this movement is controlled to a specification.

Yes, in some cases replacement hub assemblies come with ABS cables because most vehicles are now equipped with ABS. For non-ABS vehicles the cable can be cut off before hub installation.
