Name is Greg,
My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,
If the front is flashing then it has not disengaged fully.
Put back into 4 wd until it stops flashing and stays ON ,then go into "N" then place into 2wd, then reverse a few meters should then disengage and the flashing light go off.
Try this then get back to me .
