2005 trailblazer, When problem started it was a bad

Customer Question

2005 trailblazer, When problem started it was a bad vibration while driving in 2wd, really thought I had a flat tire. Pulled over to side of road and tires were fine. Pulled back on road and approximately 1/4 mile, the vibration went away entirely. My mechanic first replaced the selector switch on dashboard, probably one weed later it started popping like it was trying to engage 4wd, mechanic then replaced encoder motor, about one week later while driving in 2wd, starting popping again, one pop about every 500-600 ft. mechanic then replaced the axle actuator, few days later same thing again.
