The 2003-4 Discovery was one of Land Rover’s most successful models. Unfortunately, significant problems have begun cropping up as the trucks have aged. I’ve written quite a bit about the engine block problems, which got a great deal worse in the late 4.6 models.

This is a serious weakness that is made very apparent with the increased use of liquid snow melter on snow country roads. When that stuff gets into the mud inside a frame it stays damp and its incredibly corrosive. And the inside of the frame typically has no protection.
