Duratrac's aren't directional, so I guess theoretically I could do a cross rotation. I don't have a full-size spare right now (on my list) so I'm only doing 4 tire rotations.
I went ahead and rotated the tires myself yesterday. While I was under there I got a good look at the LCA bushings....they are all cracked and not in great shape:
I also took some video of the wobble I saw in the front tires, before I rotated. The rear tires are both straight and true as seen here:
The front tires both wobble back and forth like this:
While the wheels were off I cleaned up the mounting surfaces on all four to make sure there were no interference. I saw this weight on the passenger drum when I had the wheels off. I've never seen a weight on a drum like that.....does this happen often? I haven't taken the rear wheels off myself since I've had the truck (never had a need to, rotations performed at a shop) so this is the first time I've seen this.
After rotating the tires there is a very noticeable difference in the vibration. I can still feel it in the pedal and floor at ~40mph (much less than before) but not at all in the steering wheel now. I believe the bad tires in the back are vibrating up the driveline into the pedals. So it looks like my tires are the cause of the vibration, and the tires went bad due to bad alignment.
So, next up is new LCA's with bushings installed. Then alignment and new tires.
