I think it's possible the E450 uses rear springs that are arched opposite of what we usually think. Somebody here may be able to explain that. I mention it now because I am not sure that an E450 spring that is not bowed DOWN has collapsed. Till you have an understanding, don't replace springs on their appearance alone.

That's why I take it to a frame shop they have the trained eyes for that AND they've got these incredible mathematical calculations they work with. When I looked at the leafs they looked fine but they were not to someone who knows that stuff.
They started asking me all what I wanted and spewing all these mathematical figures related to metal at me! I told them to do what they thought was best. When all was said and done the ride as I mention was just unbelievable and as an added bonus it lifted that long rear end up too!
