Curious if anyone has replaced their seat cam reclining mechanism.  I have had mine pop back into the reclined position a few times, and after removing my seat this week, the most upright position appears to be really chewed up and rounded.  One side looks to be worse than the other, and I believe this is causing an uncomfortable lean to the right.  I couldn't find any solid leads searching through the forum.  Does anyone have a replacement part or fix that they recommend?
