Hi,
Ski season is drawing to a close and I want to add the ability to lock into 4WD.
My Aviator has AWD. It automatically transfers drive to the wheel needing it the most.
I would like to have either the offered AdvanceTrac option or some other modification made so that I can lock into 4WD for constant power to all four wheels.
Can AdvanceTrac be added after purchase or must it have been built in?
What are my other options?
Thanks,
Vic
