My 4 wheel drive is not working. No message on the dash. I replaced the front engage motor with no result. When I removed the motor I placed my finger in the hole and it met resistance that I could no move. Should I be able to feel something springing back, My truck shows it is in four wheel drive but the tires will not pull. The front drive shaft turns in four wheel drive and does not in two wheel drive. What is something I can do to figure out what is going on as money to go to a shop is tight. Thanks for any help.
