It Drove OK?? Who worked on it Last ??

This is on a GMC pickup were i work . They had a guy working on stuff a while back i found some other stuff he did that was messed up . The pickup had a cv joint on the front end making noice . i went to replace it and found he never hooked the idealer arm up. It had been like this for close to a year . They have other pickups so it was drove but not a lot. The tie rod ends nuts were lose also.
