I have an adjustable beam. It was lowered and I wanted to bring it back up to original height. My mechanic did it and a week after, the upper adjuster plate let go and it came back down. The splines on the beam are rounded so I don't think it will hold at the top. I asked the mechanic to weld the plates together but he won't do it because he says the grease in the beam could explode/catch fire. What are the thoughts out there? It needs to be welded and if someone has no problem with it, let me know.
