New front Diff.

[BIGT]

I have around 58,000 miles on 03 H2. I started to notice a vibration in the left front end a few weeks ago, so I took it into the Hummer dealer. They didn’t take me too seriously, but after 58,000 miles, I know my truck. Well, it ended up that the front differential output shaft on the left side was worn. It had about ¼ of play. Well, they replaced the entire front differential for me. Good thing I bought the GM extended warranty. They did it at no cost to me. Since I have been driving it for the past week since the repair, I feel a clunk under the driver side floor board. Like someone is hitting it with a hammer. Not all the time, but mostly from a stop when I’m turning left. Anyone have any thoughts on what it might be before I take it back?
