4wd disengage issue

Everything now confirms some clueless idiot with an impact wrench overtightened the fill hole plug. While that can be done with most differentials without problem, you can't overtighten the fill hole plug on a TJ Rubicon axle without causing the locker problem you've been having.
 
ok took cover off to look at everything....put clamp back on hose and did not put fill plug all the way so now the locker disengaged and no more light flashing as well. So all is fixed with these two issues...did not put back into 4lo and try the lockers as I dont have dirst easily accesible..( the one place I went to they barricaded and put a gate up...)
