I've got a 92 K2500 (4x4) with a passenger side CV boot that is cracked pretty good in one of its crevices. It isn't broken yet, but I figure it might be by the end of the year. Would it make sense to just replace the boot or should I go to Autozone and get the entire $65 unit? Then everything is new. Or should I just leave it and let if fail when it fails? At $65 I guess I wouldnt mind replacing the whole thing. The truck is up in the air for new brakes now, so if the CV has to come out, now is the time.
