I need to replace the ball joints on my 04. I was looking at the spicer joints on the rock auto site and was wondering about the joints that offer different degrees of caster/ camber adjustment. Has anybody used them? Do our trucks need them ? If so , what degree ? They offer . 5, 1, 1. 5 degrees of off set. My truck seems to handle fine and my tires have over 70k on them and are wearing evenly despite a bad upper joint. I need to replace my tires before winter and of course I want replace the joints first. Spicer has always been my first choice, but what are you guys using or what should I stay away from. What brand are the OEM parts? And what about these new extreme duty joints I have heard about on here, are they out on the market yet? Thanks for your input, Doug
