I would connect the tech2 and watch the abs sensor live data while driving, even though the hubs are new. If all 4 feeds are moving smooth then proceed to checking the steering position sensor. The problem with this type of issue is there will not be a code stored until whatever it is completely fails and the service light comes on in the dic then there will be a bcm code stored.
you could try doing a full module scan anyway and see if maybe it saved a history code but unlikely.
