It's made of pretty thin metal, maybe 5/32 thick. I remembered tonight a few weeks ago, when I backed up with the wheels cut all the way around, I heard a faint snap a couple of different times but couldn't get it to do t again. I'm thinking now that might have been the start of it breaking. I never checked the bracket bolts to see if they were loose, I was so disgusted when I saw the whole diff floating and the cv boot tore up, I loaded it on the trailer to take to the dealer tomorrow morning.
I've only used the diff lock couple of times since I've had it and that was last winter in snow and never used the override. I don't jump it or race it and go around mud and water if I can. My son gets ticked at me when I do go riding with him cause I go to slow.
