I was greasing my rear suspension bearings last night for what i think is the 5th time since i have this bike. I did it a little different this time, i took the rear linkage last (with out leaving it on the swing arm) and when i put it back on (first) i noticed it would move about an eighth of an inch on the sliders. I know i did not forget anything and to be sure i removed it and made sure all the spacers were in. Since the other times i did this i put it on with the swing arm i would not have been able to see this movement, my question is, is this normal. there is no play up and down the movement is very smooth. Input only from people who have done this is what i am looking for. Thank you in advance.
