Hey guys, been a bit... here's a new one for ya, We've got the vehicle listed above in here today... the AWD light starts flashing as driving... we live in Jersey so it's mostly highways... and ideas of where to go on this one? Is it a light thing or is the AWD malfunctioning? Thanks in advance... scanning produced no codes just drove it again and the lights not coming on.... only thing he can see that's wrong is back left wheel in photo... could this trigger it? He doesn't want to do it and it not solve the problem.. plus there's a ton of rust under there...

A broken tone ring could trigger it on but I would expect the ESC light on with it as they both use the same signals. Take it out on some rough roads and see if you can get the light to come on again. Maybe record the speed sensor outputs if possible. See if it's dropping out.
