No problem man. I had the same debate when I installed mine. I installed them myself too so being used and my first time installing them the odds weren't good that they would be perfect. No problems though. I even took it to a shop a few months later to get it checked out and they said th ebacklash and everything was fine. good wear pattern as well. they changed out a bearing that was bad though. Make sure you get all new bearings too. If you have questions about your trac loc get that rebuilt too while you are down there. I didn't do mine because I didn't get the parts in time. GOod luck
