Review on Dorman 697 706 GM Differential Cover: Ultimate Protection for Your Vehicle's Gears by Adam Gechem

This is a great rear diff cover. I didn't like that there was a drain plug. But for the price. It's impossible to win. I've noticed that a lot of people complain about the drain plug leaking. So I definitely understand why it happened. I didn't have the drain plug on. It wasn't much. But not tight enough to prevent leakage. Therefore, before installing, tighten the drain plug as much as possible. Otherwise it's a good case that I'm sure will last a very long time.
