Alright so I did a little on the truck last evening. I first jacked up the front end and checked ball joints, tie rods, trac bar, steering box, wheel bearings, etc. Nothing found. I then spun the tires by hand and watched them near the ground and sure enough the left front looks to be out of round. So I pulled it off and threw the dial indicator on the hub and there is only .004" of runout so that is fine. I then put it on a jack stand and put the rear on jack stands. I then used big wheel chocks on the right front and put the truck in gear so i could watch the rear tires. Both looked great no out of round look and they are straight to. So I rotated front to rear and then did the same thing and now the left rear looks out of round. The right rear looks great. So 3 tires looked perfect and the one does have some out of round to it. And its not any front end parts since it is identical on the rear. So I then finished up and drove it home and did some freeway and it is nice and smooth now, however the rear you can now feel it in. So today I will have to make some phone calls and see what I come up with. Get it thrown on the road force balancer and see what the out of round specs are.
I am also thinking of adding a little caster as well. and possibly toeing it in another 3/32" or so. But First will deal with the tire issue.
