i was going down the road tonight and my truck made some loud noise and my rear end locked up and skided to a stop i broke the pinion in half and froze the whole rear end has this happened to any one else and do you think i will have a problem with warrenty with all the stuff i have done to it also if you look at the pinion you can see that there was a air bubble in it cause about 3/8th is smooth and you can see the wrest of it looks like twisted metal
