My 14 Armada with 145k miles has started showing the abs slip and 4wd lights intermittently. I've read a lot of forum posts stating a bad wheel bearing or speed sensor but these are mostly for older models. Brought to dealer and they are lost. After 4 hours I received a call saying it may be the awd system but they're not sure yet. I have not read about this with any other Armada with that problem. Vehicle drives and handles normal. Have not noticed any wheel bearing sounds.
