Tires are Westlake LT265/75R16 Load range E After a little research I see that Westlake isn't all that great a tire.

I'm going to go back to the last shop that has balanced my tires twice.

Haven't pulled the trailer yet and yes, the problem is on any road other than one that might be a little rough.

If the tread is separating and not causing any shimmy or side to side force, the standard tire balancing machine may not pick it up. Shimmy is usually cause by a warped or bent spindle, although excessively worn front end parts can cause it.

My truck has always had that kinda of bouncing that you are talking about, it was explained too me by my tire shop guy that it's the speed at which the tires harmonic's causes it too bounce, happens even when I slow down and the truck is passing through that speed area of 45-48mph. Nothing you can do about it

ALIGNMENTS DO NOT CURE SHAKES ,BOUNCES AND SHIMMY. THIS IS CAUSED BY( oops sorry about the caps not yelling! ) out of round out of balance , bent or ply seperation. I have seen this. you rotated the tires front to back, it is poss that two tire same side hit the same pothole at high speed two tire have ply sep. rotating did not help. As far as the steering return to center do you have the read out from the alignment shop? can you post them if you have them. also if your new joints have grease fittings pump some grease in them till the dust boots just start to bulge. you really have two seperate issues going on here.If you can get the truck on a lift and spin the wheels and look of any out of round in the wheels. or last resort take the truck to the tire shop and see if they will put a set of tires on it and go for a road test to see if the problem goes away. good luck

Steering is much better now. Two shops told me that it might take a few miles to get it to happen. As for the tires, rotated twice and balanced twice and the tires are like brand new with maybe 1000 miles on them if that.
