4x4 won’t engage

I have a 2016 Ford F-350 6.7. We just changed the hub assembly and upper and lower ball joint. Had a front end alignment. Went to use the 4x4 today the light lights up on the dash saying it’s on but the 4x4 won’t engage. What could be the issue?

vacumn hose disconnected or the motor that engages the transfer case is not working.

I would first manually lock your front hubs and see if that changes anything.

Also with he door open if you switch to 4Hi you should be able to hear the motor for the transfer case do its thing.

Try manually locking the hubs.
