I think you need one or more new air shocks. Let you dealer make a suspension test and you'll be more clever aferwards.
BTW, my rear right shock died after a hub beering swap. Take a look at the picture below(sorry for the bad quality) where you can see the RR shock working at just 5%
Thanks for your help Brio after seeing your test results, I will request a test.
