If the rear is creaking the chances are it’s not the linkage or lower shock mount, but the swing arm pivot itself. If it’s the same as mine, when the pivot nut is even remotely tight (40nm) the swing arm binds on the outer seals/shims which is what is creaking. Mine needed a 3mm spacer, so when everything is tight the shims control sideways movement of the swing arm, but don’t distort and bind with the swing arm. There’s a YouTube vid which is helpful.Today I went around the bike checking a fww things. Three spokes needed a half turn to tighten them (two front and one rear). I have a creak on the rear suspension so I loosened and correctly torqued the swing arm bolt. That didn't help so I've soaked the rear shock bottom bolts and link rod bolts with penetrating oil to see if that helps. If not, I will have to dig into the bike and remove the shock and apply lubrication where required.
