leaking from the diff side, both boots torn on both sides, and only 12k miles on them. id like to go back to OEM. those lasted way longer with no problems. I figure if I'm already ripping into them to the diff, I might as well put in the equipment I hope will be problem free longer.What is wrong with the cv axles? if boots torn, just go to toyota and get a kit, it will come with boots, bands, and grease. Not a bad job, a few hours and getting dirty.
