Completely new to the GM forums but I'm down to my last straw with servicing the family vehicles so i figured I'd give this a try. So I have a 2004 2500 hd sierra 6.0 4wd gas engine and as i was inspecting my next project under the tires i noticed that my front left cv axle (driver side) had a half inch or so gap where it connects to the front diff. and I'm curious as to whether or not this is normal or if it is supposed to seat all the way to the front diff. I can say this, that the visible gap that i encountered looked like the axle was very clean where it was seperated leading me to believe that it may have slide out of place exposing the clean half inch gap that i visibly observed. To me (an untrained and unexperienced diy mechanic), it doesnt seem correct and instantly threw red flags for me, enough to jump on here for help so hopefully someone can chime in with more knowledge than me and possibly provide assistance. Much appreciated
