Saw an episode of Air Disasters that covered a couple instances of the 737 losing motors like that. It had to do with the method of motor removal for service that Boeing did not call for. To remove a motor correctly they had to remove the mount to the wing and was very extensive. Instead, mechanics found a way to remove the motor while leaving the mount in place. Removing it did not do the damage but lifting the motor back into place stressed mounts as they were banged around to get seated weakening them.

Love that show.
