... okay so I installed Stinker's drop shackles the other day with no problem. But now I have this awful squeaking noise when my rear suspension goes up and down. It even squeaks when you push down on the rear bumper without much effort. I put it on the lift today and removed the bolts that hold the shackles to the leaf springs and greased them and replaced them. Made sure the grease fitting on the shackle itself was greased, it was. Let the truck down and...... still the same loud ass squeak! What else would it be? TIA
