Lower rear linkage bolt cracking the frame?

[nmcguire]

Hey, just wondering you anyone has had this issue. The lower pivot bolt that connects the rear triangle to the front triangle has a fair bit of movement and has caused my frame to crack. I have had this fixed by a carbon repairer and overhauled all the bearings as they were seized and replaced the through-bolt but there is still movement and i am worried that it will crack the carbon frame again making my bike essential worthless. Has anyone experienced this and fixed the issue?
