I'm in a 14 z71 and was doing exactly that. On freeway couple days ago sudden extreme shake and bam front axle bearings exploded through the boot. I replaced axle but front passenger side wheel seems to have solinoid locked . wont spin when on jack. I have service 4 wheel message but no codes showing on basic reader. My battery was tired already so i replaced it just to rule out low voltage causing it. And I read somewhere not to shut off truck in auto . I tried to remove battery and hook cables together to reset the truck but service message immediately reappeared before I even started the truck. Somebody has to know. I'm efficient at electrical and am covid broke . how can I wake up the encoder motor or find out if it's bad?
