So I've got an old set of 460Ds on my bike and for some reason the left side pedal clicks.

I had greased the bearings and reassembled them and it was fine for a while, then it started clicking so I regreased and reassembled and again it was fine for between 50-100 miles (I don't keep track) and now it started clicking again.

Is there some trick to these things? The right side doesn't do it, should I use a drop or two of threadlock on the nuts so they don't loosen or does it sound like something is worn beyond hope?
