Ah, that makes sense. I had my 2013 TR in pieces today, to grease the pivots and try to sort the creaking. In the pivot just above the BB there are 2 thick (plastic i think?) washers either side of the frame/seattube. They sit between the frame and bearings set in the end of the chain stay, in a recess. I thought it was odd they're above half the size of the recess they sit in.
Guess they'll just send out the correct size washers. Easy job to fit. Hope that sorts it, the creaking/cracking noise is getting louder on mine each ride.
Just hope CRC can sort the issue with my very noisy shock too!
