Question about Cars & Trucks
Check the bushes / bearings that are in the end of the diff housing for shaft wear. Check the cv joints for wear. check shafts for bent . check front wheel bearings and adjustment. Check the drive shaft from the transmission to the front diff as they are prone to u-joint failure and excessive wear in the slip joint.

Well you can remove the sensor in the diff and make sure that looks ok they g obad quiet often also woulnd not hurt too remove the rear diff cover and inspect the rear end if it is whining and you dont see anything wrong i would refill it with lucas oil/grease and start praying check the pinion too and see if it has any play in it

the trailblazers are designed to shift from 2 wheel to AWD on the fly. BUT NOT TO EITHER OF THE 4 WHEEL OPTIONS. I'd suggest you get it to a mechanic to evaluate the damages.

I had the same thing happen. The automatic locking hubs are faulty, causing one or both hubs to try to engage or disengage onto the front driveshaft. This makes the clicking noise and loud clunking that you hear. You may notice your steering pulling to one side of the road,because one hub is locked in. Replace the automatic hubs with new ones, do not try to fix the old ones. I liked the
convience of automatic hubs but replaced mine with manual hubs, there just way more reliable.
