Is something actually broken? I am not a suspension expert, but it looks like in the top picture the U-Bolt is loose. Are you able to tighten it?
Jayco installs the helper springs as a part of their J-Ride package. Not sure if Jayco was calling it J-Ride in 2010 or not. Our 2009 had the helper springs, but Jayco wasn't calling the system J-Ride yet. Any competent mechanic should be able to work on it. It isn't under warranty by either company, so I'm not sure why either won't work on it.
If you have a shop that works on big truck suspensions, they should be able to help you. From the picture, it looks like the U-Bolt just shifted. Shouldn't be hard to fix, even if something broke.
