Thanks for all the replies so far everyone.
To the guys that are having the wobble/shake just in general while driving straight here is my one piece of advise...
We all know the front ends are very sensitive to any imbalance AND putting on larger tires may magnify this issue. By no means am I am an expert but I work at a local off-brand high end dealership and know a thing or 2 about mechanics.
I tried an old trick on my last alignment that has seemed to settle the wobble/shake when driving straight for the most part so far.
There is play in the front end/wheels left to right on our trucks. Maybe even a bit more than I had initially thought. I believe one part that attributes to this shake is the toe angel of the alignment. The larger tires also magnify this due to play in the tires and play in the steering.
The trick that helped me was to first set toe left and right to zero. Then apply a good amount of force to the drivers side tire with my hands turning left and then turning right. I am doing this while steering wheel is locked into straight position. When doing this initially I got my drivers side wheel was about +15 degrees to the one side and -15 the other side which was about perfect. When going to my passenger side even though the toe was at 0 I pushed one side and got -30 and pushed the other side to +5.
So what happens is the front end binds up slightly when sitting static on the alignment rack. You turn the wheel left and right upon setting up to eliminate this however that only does so much. So basically when driving under load there is a good chance my drivers wheel was going straight and passenger wheel toed inward to much and causing extra force to that side thus getting a shake/wobble/imbalance.
I adjusted the passenger side toe until I was able to get it to match the driver side roughly -15 and +15 pushing left and right with the same amount of force. This has seemed to cure my straight line wobble/shake. Still not perfect and I can feel it come back slightly here and there however this has minimized it greatly and truck tracks straighter and drives smoother than before.
I do believe that a proper alignment done in this manner should at least help the situation for everyone else as it has definitely helped me.
However I am still trying to figure out this wobble when returning to straight... Still have gotten nowhere with this issue.
Thank you,
