Quick question concerning pedal

bearing is AFU, rusty, etc. You should be able to swing them "with you rlittle finger"
Is there an easy way to replace that bearing? I can see a couple bolts that look like they're holding the hinge in place, though I've heard removing the pedal is a big ordeal.

If spraying it with some wd40 would fix it (at least temporarily) that would be good too.
