Crawled under my runner to check things out today and noticed a bunch of oil around the inner CVD also seen the inside boot is torn this was replaced 2 years ago and I have lifetime warranty on it so I'll swap it out again but what concerns me is the in/out play which is about 3mm 2x that of the other CVD. I don't recall replacing the seal the first time I did this swap. Is there anything else I should look at? Will do the CVD/deal swap next weekend.
