genuine gear exchange at 4wheelParts
my rear pinion gear basicly blew up and since it has a lifetime warranty we took it back to 4wheelparts to get it exchanged (genuine gears)
we walked in and the manager looked at the ring and pinion very carefully and said that he wouldnt be able to exchange the gears, because from the pattern on the teeth of the ring gear it was set up wrong.. soo after a while of arguing that it was set up wrong my dad said we'd just buy another kit so the sales man brought out the new ring and pinion gears
examining the new set on the counter, the first thing we saw when we opened the box (genuine gears-same brand) was a card that said "LIFE TIME WARRANTY! break it, burn it up, blow it up! NO QUESTIONS ASKED!"
i thought it was pretty funny
