Hey all, sorry if this is the wrong area. 2008 Suburban 4WD here and I bent this weird clip on my u-joint, curious if I need to replace u-joint or not? I have 4 u-joints and only the one on the front diff has it. Very thin metal that I can’t imagine does much. New ones don’t come with it. What’s this things purpose? Can I just pull it and forget it? Never seen one of them before anyway. Thanks guys!
