I never realized with all of the times that I have used a grease gun that the tip adjusts to lock on the grease fitting. I got it on like normal but when I went to take it off it wouldnt come off. In my struggle to take it off the nipple broke off the front -left- lower a-arm. Should I jb weld the fitting on or sould I drill the resst of the thread out? The simple fix would be to jb weld it on. I would half to take the arm off to drill the rest if the thread off.
