I lifted the rear end of my Tacoma with an add-a-leaf system and cannot keep the leaf springs to stay lined up. They keep spinning around the center pin. Know any remedies for this? I tightened the U-bolts so that is not a problem.

 

if they are between the u bolts there is no way for them to spin around the center pin... there are some leaf bolts you can get to minimalize lateral shifting... they look like a little mini flat u bolt

 

So is the center pin to blame? I don't want to have to take the leaf pack apart again to see if the pin is gone unless I don't have to.
