Alignment/Tire Wear Experts Help Please

01 Pete 379L, 244" wheelbase, low air leaf, my drivers side steer tire started to wear the inside rib, and now a few thousand miles later its also starting to cup on the inside rib, pass side is wearing nice, king pins feel tight, felt the shocks tonight and d/s was cold so prob no good, pass side nice and warm. My reason for concern is the pass side rear rear duals are wearing faster than the rest, more pronounced on the inside dual, checked the main bushings with a bar and they feel tight, shocks feel good, only real problem u can actually see is the torque rod bushings are starting to look a little sad, I'm just wondering if the driver side front cupping and the pass rear wearing could be related in any way because of thrust angles, etc? Truck handles nice on the highway, pulls to the right a wee bit but nothing drastic.

 

Hard to see in the pics but the rears are worn around 3/32 more on the pass side

 

Torque bushings and front shackles, shackles have a bit of a gap, greased last weekend, 3000 miles this week

 

Michelin xze2 on the front, Hercules h302's on the back, all the rims and tires have around 50,000 miles on the, I used the truck for local, mostly off highway work until just recently went back full time long haul, I know this tire combo isn't the greatest for highway, but when plans change basically over night u run what u brung lol, pulling super b trailers, grossing around 139,000lbs

 

Pulled the shackle sides off, the gap is from the washers wearing into the alluminum, bushings are shot but I flipped the sides over so at least they are tight for now
