Little update for you all. I am chasing down a creaking noise in my Deavers. I have no idea what it is coming from. It seems like I can only hear it when I'm going slow and the bumps are small. Definitely a creaking, not a squeaking. The bushing seem to be lubed properly and nothing visually is wrong. I jacked it up from the rear and sprayed water in between then hoping to clear out any debris. While the springs were wet there is no noise, but when they dry it comes back.
I spoke with the guys at Deaver and they said the shackle bolts are too tight. I sent them a video of what is going on and they said it sounds dry and tight. Confirmed it is not dry. The RPG shackles are to be torqued to like 163 foot pounds I think it is and Deaver said no more than 60 pounds which doesn't make sense to me.
Before I spray the leafs with some type of dry lube, I think I'm going to take it back to the shop that did the work and have them figure it out. But doing that adds a whole element of logistics with work and kids and all that.
