    hollowtech II left arm "click" keeps returning

    I recently installed a new Shimano 105 FC-5603 (triple crank). After about 300 miles I started hearing a faint "click" when my left crank arm was at 12 and 6 o'clock. Having troubleshooted square taper cranks for a few years, I figured something was loose on the spindle/crank arm connection.

    The fore and aft 5mm pinch bolts were slightly loose. So I was more careful to make small, even incremental turns this time. That got me another 120 miles, and I'm starting to hear the "click" again. When I got to work today, I tested with my mutli-tool 5mm wrench, and the pinch bolts did not seem loose at all.

    I was extremely careful to grease and really tighten the BB cups, so I'm confident my issue is specific to the crank arms. I've also followed online docs:

    Anything else I'm missing? should I use loctite or use more/less grease in certain areas?
    Thanks

    Did you check the pedal threads for looseness? Possibly they need grease too.

    My Tiagra crank did the same, seems i'd tightened the plastic bearing preload cap just a little too much as it went away when i reinstalled and made sure to tighten very gently.
