I have a pair of old Shimano SPD M-520 pedals on my bike right now. During last few days of my long ride last month it develops this "click" feeling during the down stroke of my right pedal. It seems to now be very consistent. If i grab it and give it a twist and it seems to move side to side more than the newer pedals on my other bike.
Is the bearing going? If so is there a way for me to adjust / rebuild it short of buying a new one? I can get a new pair on ebay for under $40 shipped. Is it worth trying to adjust / rebuild it? I have plenty of tools, but none of the pedal-specific such as park PD-40 tool to remove the shaft from the pedals.
