There are many components to your 4wd system. Depending on what is wrong with the system, it may be anywhere from a few hundred to a few thousand to repair. Have a qualified technician diagnose the system and go from there. There will probably be a diagnostic fee for checking it, but they should then be able to give you an accurate estimate for what it would cost to repair.
