As in any FWD cars you drive, whether it is Honda Accord, Toyota Camry or Volvo 850/S70/V70 etc. etc., the single most important thing is to detect the OUTER Boot crack early in the game. This way you can save the CV Joint itself. Once the boot is torn open, debris, dirt, sand etc. get in the CV Joint and can damage it very quickly, within a week or so. So be proactive and replace the boots as soon as you see deep cracks (superficial crack is probably normal after some 50-80K miles). As long as the CV Joint itself is protected, it should easily last 200K miles.
