Don't worry about it, it's nothing else, nor is it uncommon or even time sensitive. My stock CVs did that right after I put my first lift on, same color grease. I put hose clamps over the stock clamps and that worked for about 2 months, then the boots shredded and I duct-taped them up and I drove it like that for another 8 months or so through an entire winter using 4wd most of the time. Take Elton up on his offer and I recommend the CVs with free lifetime replacement from NAPA.
