I have an 06 4x4. Replaced the shift motor, solenoid, have vacuum that holds preasure, and checked the actuators. Everything seems to be working fine. Axle turns in 4x4 and not in 2wd but there is no grab in 4x4, the front wheels will not pull. Pulled off actuators and they work, when it is jacked up the wheel and axle spin. Any help would be appreciated. I am a new subscriber but have used the site for many other problems
