Hope someone can answer this. I was under my car and there are two flat aluminum bars, each about 3-feet long. They have something to do with the front end alignment or stabilization. Anyway at the front end of the each one there is a vertical bolt that looked loose. So I commenced to tightening these bolts, but now I'm thinking they were probably for the front end alignment and not just two loose bolts. Do I need to go to the front end shop?
