Usually, this occurs only once and most often, right at the beginning of a trip. However, on our recent trip, we were forced to drive for about three miles on a very rough, washboard at times, gravel road. The popping was incredibly frequent on this road, but MUCH lower in volume. As soon as we returned to pavement, the popping stopped. This obviously points us to something in the suspension, but we've not heard anyone who has described such an issue.

We DO have Sumo Springs on our unit, but other than that, our suspension is stock.

Anyone else have anything like this?

Have you checked for sufficient grease in the front steering and suspension fittings? I heard some popping underneath and found a lack of grease. Filled up the grease boots and the sound went away. One of the grease boots was dried and cracked on our brand new motorhome. Took it to Ford and they replaced it under warranty.
