I have a Husky round bar set up that I've used for 6 years. On rare occasions a bar will pop off on a sharp turn. Just returned from a 900 mile trip and one bar only popped off 4 times. When I unhook from the trailer the bars seem to have a bit of slop in the main housing and I can wiggle them loose pretty easily, especially the one that came loose 4 times. Do these things wear out? I've never lubed them. Ideas?
