Well I have toasted another Lockright Locker. My first one was defective from the factory. The teeth that engage the coupler to the driver ending up shreading a bit. It wouldn't stay locked. The 2nd locker is totally locker. It turns out I have sheared the 4 pins in it. I am not sure how I have done this. I am running 35" with 10 bolt axles, stock 350 and Lockright Locker only in rear. I have been 4wheeling right thru the winter. We don't have much snow. And I have been pulling out some fullsize trucks that are really stuck in mud & ice. I broke a 18 000 lb strap one trip. Is this abuse cost me the locker? And has anyone else broken there Lockright like this? Thanks for your help ahead of time!
