I have a 99 silverado with a 6" suspension lift and 3"body lift. The shocks were recently replaced but coming from the front wheels I here squeeking when I go over bumps and stuff. When in parking garages I noticed that it always squeeks. I was just wondering if anyone new what I could do to fix it. I was thinking it might be the spacers on the front for the body lift? But also some bushings on some part of the suspension. Do I need new bushings? Or can I just put something on them to stop the noise? Thanks
