I recently replaced the lifter struts that support the back window on my 2003 Blazer and when I travel around 50mph or higher I hear an awful rattle and vibration. It sounds like something keeps tapping the back window. I've checked to make sure I put them on correctly and I don't see anything that I did wrong. Any ideas or suggestions? Thanks!

 

Even though our trucks tend to rattle and tap alot more than the next I would suggest checking the seal around the window, for and cracks or missing parts of it. Then try cleaning the gasket up I know someone put something up on what to use, can't remember what at the moment. Maybe someone will post up what im talking about when they see this.
