Can missing wheel studs affect 4wd?
My car has 150000 miles.
My car has an automatic transmission.
In most situations, I can’t think of a situation where missing wheel studs will prevent you from engaging the four wheel drive system. If a piece of a broken wheel stud falls behind the flange, it can cause the wheel to lock up, but even then, it shouldn’t keep the four wheel drive system from engaging. Keep in mind, missing wheel studs does create a less safe driving condition, as the vehicle is designed to use all of the components together. If there is a situation that you feel you could use further help with, I would suggest contacting a certified mechanic, like those available at YourMechanic, to take a look at the vehicle and make recommendations on how to make repairs.
