"Bushing bind?" Leaf spring bolts/shackles: how tight?

Thanks, guys.
Yeah, I’ve definitely been driving around at way over 35ft/lbs of torque.

Good call on the grease. I used the lithium goop that came with one of the suspension components but I could probably benefit from another application.

The bolts on the spring perches toward the front of the car...anyone have a torque spec there?

Thanks!!!
