My ABS light came on the other day, it stays on, the front bearing fried it, purchased new bearing/hub assy. but can't see how to grease the bearings before I install the assy. looks like a sealed unit

 

i know this is an old post but i had the same thing happen to me and i have replaced both assemblies and the ABS light will not go off. i have tried leaving the negative battery cable off too. anyone have any ideas what it is?

 

anyone?
