Why do my rear LCA bolts keep falling out? I see a lot of posts but no one ever really answers the question. I have the stock LCAs and bolts. The truck is lifted 3". More flex? The UCAs are fine. The LCAs are loose again. One shop told me I needed new Toyota bolts and they need thread locking compound applied while they are being torqued. I came close to losing the drivers side and the passenger side was on it's way out. Is this a common problem when lifting a FJC?
