padding on bottom joint
check top joint for movement, sometimes the bushings are a little smaller than the holes, like my left one, currently finding a solution that doesn't wear off after an hour
squeeking can come from the joint immediately under the footplate, or the one with the T shaped plastic, just bushings squeeking from pressure usually, lubricate with something suitable should make it sound nicer, silicon dry lube or something should be good, not standard oil though
