I have a 4.2L 4x4; the fan is not stable it is wobbly. After researching online and ruled out the fan clutch, thinking it was the bearing behind the pulley that needs to be replaced - I noticed a crack on the block behind the pulley

Water pump is what you are referring to. Yes, it most likely has failed.

As far as the crack, can you post a picture?
