It just started doing it this morning. There is a loud ass creaking sound from the right caltrac metal bushing.The one that gets pressed into the leafspring. It's not the usual squeak, that noise I learned to live with. This is a loud creak any time the truck moves and it's definitely coming from that metal bushing. Any ideas? Please dont tell me it's normal. When I did research on theses, I read about the squeak. And that's tolerable. This creaking is gonna drive me nuts.
