If you are in the area or can travel to MORryde have them check your springs, their service shop is second to none! We were just in for a "routine alignment", the tech spotted two bad (torn) springs, we had to have them replaced. Keep in mind there's a 5 year warranty on those, they replace "N/C" if you're within warranty!
MORryde treats you like royalty while you're visiting their service shop! Beautiful waiting area, beverages supplied, lunch IF you're there that long AND a T shirt! Oh, and WIFI too.
