This topic has come up in a couple of threads, and it has been noted that greasing CV's is on the nissan schedule every 40k. My vehicle did not have it done at 40k at nissan, I didnt do it at 80 just after I got it, and now its nearly done 120k. I have done the 120k service, including wheel bearing repack, but not CV's yet. Will be doing it shortly. I use 4wd regularly, at least every fortnight, beach runs, and sometimes up to 100km slippery dirt tracks. What about others? How often do you service them, and how much do you use 4wd? I began to think about it cos for the first time I can now feel some vibrations in the drive train when using 4wd and got to wondering when the CV's get greased. Cheers...
