Hey guys my neighbor has a grand cherokee and wants me to do some work on it. He says the front end makes noise when he turns corrners and I did a visual and didnt see much that would cause this except that the steering bushings seem to be going and some are gunked up and has grease coming out of it. The worst spot i noticed that i think is the problem is the one that comes off of the steering box.

My question is how hard is this to change and does it sound like im on the right track with the steering linkage?
