I don’t know if this is the right spot to ask, if not just let me know. I’ve got a 95 k1500, I’m new to owning a 4x4 but have done everything I can find online on getting my front wheels to lock. I have the floor 4x4 shifter, I can easily put it into every option, the transfer case does lock when I put it into 4x4 but my front wheels won’t lock. Actuator (electric) works fine but I’m out of ideas on what won’t let the front differential to lock the tires. Is there something I’m missing or I can check??
