How do I recognize defective cathedral bearings in the back?

Maybe I’m spoiled by my Mercedes w202 or my little one still has something. Feathers rather hard, in the curve in unevenness there is a rum, I can’t describe otherwise. Shock absorbers are new and I’m not sure if I’ve kept the 95 degrees exactly. Was only so feeling. At the cathedral bearings I couldn’t see anything, the metal sleeve is not firmly connected to the rubber or? Wouldn’t I get any other input springs and plates up and down as well as also Remake and look at the cathedral camp. Rejoice me on every suggestion. Lg Thomas
