Why do the sway bar links on a Mercedes fail so quickly!

How i replaced sway bar links that are worn, clunking, clicking in a Mercedes-Benz C-Class W204 C204 S204 C250 C300 C63.

Where I bought my parts:
www.FCPEuro.com
(I think they still offer a lifetime warrantly. If there part fails, just buy a new one from them, send them the old one back for a credit)
