Resurrecting an old thread...
I'm in the process of relubing and adjusting a nearly new pair of Shimano M324 pedals that developed some play and a rockcrusher like sound.
So far I have one pedal disassembled, degreased, regreased, and reassembled.

Thinking about it now, I'm wondering if I had that back to front because the outer bearing is probably larger. I'm not pulling them apart now.
The Shimano exploded view specs 62 bearing balls - which is for a pair of pedals. It shows 14 balls for the inner bearing, and 17 balls for the outer. That's how many were in the pedal I've relubed.

I slipped the pedal's plastic bushing over the spindle, and held it about 1cm away from the crank side gasket. Then I filled the gap between the bushing and spindle with grease. Next I loaded the inner bearing balls onto the spindle around the end of the bushing. After squeezing some grease into the pedal housing, I carefully inserted the spindle (w/ balls and bushing) into the housing, and gave it a twirl to seat the balls. At that point I was able to remove the spindle leaving the balls and bushing behind. I made sure the bushing was seated, added some more grease, reinserted the spindle, and went to work on the outer end.
BTW, I found the special TL-PD33 tool at biketoolsetc. It cost about as much as a new pair of M324's.
