creak from front leaf spring eye

Did you originally torque the leafs with the suspension on the ground . If not loosen everything and retorque. And if you did it correctly I would still loosen bolts and retorque. I have had the same problem. Also depending on which front spring eye bracket you have it may not be compressing enough and you may need a little bit more torque on them. I have had this problem when changing brackets. Just make sure you torque with weight on wheels its not easy but it has to be done that way. This has worked for me with the same problem hope it helps.
