How do I know if my 4wd is working?
Hello I recently got a 2001 Ford Super Duty F-250 Crew cab Lariat V10 (Gas) truck and it has a knob on dash to put the truck in high 4wd, low 4wd and 2wd. Im new to the truck game and I am curious on how i can tell if my 4wd is working. When I turn it to 4wd i hear a click but are the hubs supposed to turn or not? Mine dont turn I only hear a click as if they are engaging. how can I tell if the 4wd is working? Please help me out if you can. Thank you in advance.
