So my Pete rides extremely rough on the front. I am trying to determine if my shackle bushings are junk. I measure the angle of the shackles when truck is resting, then jack up one side until tire is about 2" off the ground, angle doesn't change. Repeat on other side and exact same scenario. I would think the leaf should flatten atleast a little bit???

Worn bushings usually make creaking and popping noises when turning at low speeds, especially while backing.
How many miles? If you are replacing bushings ... it is only a few bucks more, and much much easier, to just buy spring packs. Replace the pins and shackles if you are over a million while you are at it. -
I am getting no weird noises, just a crazy rough ride, I would feel a mouse if I ran over it. I assumed if jacking up one side the leaf would compress some causing the shackle to move. I am concerned that the shackles are no longer pivoting when the leaf compresses while driving. My bushings are not greaseable either.

shocks are brand new. distance between shackle bolts is the same on both sides. 3 3/8" I just bought the truck recently. It feels way over sprung.

Forgot to mention cab bushings. They will effect the rideRubyEagle Thanks this. -
steers are wearing great. I checked the king pins when I bought the truck 3 months ago and all were good. Been chasing this rough ride issue. I feel the truck is over sprung. I have owned 7 trucks, and this is BY FAR the worst riding. My next step was changing out the cab bushings, but I feel its way more than that. I wouldnt be surprised if my steers have left the ground at some point due to just normal bumps on the road.
