I decided to finally do something about my torn CV boot so I looked around the forums and found this thread. From what I've read it sounds like some of you are worrying about driving with a torn CV boot for more than a day.
Now I have next to no knowledge about CV joints and axles but that boot (inner-right) has been torn like that ever since I bought my vehicle 2 and a half years ago... Is that bad?
As you can see, I have not, by any means, kept it clean down there. I've taken it on countless trips up on logging roads, over rough rocky roads, through deep snow and mud, and a few deep puddles. Yet I've never noticed any problems with it, my Runner drives fine in all gears both 2wd and 4wd.
