Hey Robert, so shackle nuts don't need to be super tight as they are designed to allow the suspension to move. So the trick is to use lock nuts with nylock (you have them currently) and then tighten them down to about hand tight with a proper sized wrench/ratchet and then back it off 1/4 turn so that it can move like it needs to.

Hey Robert, did adjusting the shackle nuts as suggested work out for you? I'm curious to know because it could help others with similar suspension setups.
