I am running headers, the vehicle is at stock height according to the service manual. The mechanics at the local shops can't figure it out and the parts stores say it's the geometry of the suspension. I've only had one idler arm from NAPA that has lasted longer than a year. I even re-lube it as they suggested. Every three months when I drive it regularly. It's very frustrating. I'm considering going to PST or Just Suspension to get a whole new front end kit. It just costs an arm and a leg and i'm trying to avoid it. Thanks for the reply!
