Thanks everyone for your comments and Longbox55 for the "easy to understand" instructions. I put my truck on jacks last weekend and reviewed. When the wheels were turned to the far right or far left the wobble was most noticeable. I kept jiggling it to see where it was loose. So would you all say this is tie-rod ends? When I adjust this should I remove the tire then? I've been phoning around for replacement tie-rod ends and not a single place has it. One guy even laughed at me on the phone.
As for the rocks, they were evenly placed in the back as one layer and not too many. The sway happens with or without the rocks. Rusty Rod, the rocks were a mix of granite, a reddish/pink, some blue-grey coloured rock between Vancouver and squamish where they have recently been doing blasting. Here's a few pics of the highway construction:
