After my lift was installed, I noticed and thunking noise in the rear every time I would go over speed bumps quickly. it sounded like something was slamming into the tub or something.
Anyway, I poked around and didn't see anything this first time.
Put it out of my mind for a while until today when I was checking the torque specs of the lift components and body lift........
It appears as thought both sides of both rear shackles are slamming into the frame. These are new shackles installed with the lift. What causes this? As I understand it, boomerang shackles are the remedy for this but can I fix it without buying new shackles?
