The old diff grenaded and my spider gears gave out just like the one before that. I was able to install the new detroit locker trutrac in about 6 hours, really straightforward to do it all. So far this didd has been a beast, i just let it rip and it just takes it with no issues. I hope i have a long life with this diff. It works exactly as designed, not to mention it weighs like 5 or 6 pounds more than the old carrier. More bang for your buck.
