  1. 3rd pinion seal leak

    Last long but started leaking again. I had to take to truck in for the emissions recall anyway, so they replaced to seal again. A few days later I installed a Mag-Hytec diff cover. We'll see how long it last this time.
  2. 2nd pinion seal leak

    Second pinion seal leak. Seal didn't last long after first repair. The yoke had a nick in it and cut the new seal. This time the seal and yoke were replaced.
  3. First pinion seal leak

    The first pinion seal leak. Dealer replaced seal only under warranty. It didn't last long.
