WARN has the reputation of being the best, but I have to question that after reading the thread last week with lots of members reporting that their mounting holes elongated and the bolts come loose?
I might be jinxing myself by saying this, but my AVM lockouts have taken a beating with a front locker and so far I haven't had any issues with cracking, loose bolts, elongated holes, or anything else. AVM 5 bolt lockouts are steel or cast iron where they bolt to the hub, and the outer part is aluminum. I think the WARN hubs are all aluminum(someone please tell me if I'm wrong about this), which might be why people on here have had so many problems with them?
Is that cracked lockout of yours stock? It looks a lot like my factory ones that have been taking up space in my basement. I never had any problems with them either, but I couldn't pass up a sweet deal on a clean used set of AVM's when I ran across them.
