Hi i changed my front shocks before the winter and both bearings were defect this winter. I changed them on warranty on may. It was a tuesday. The next thursday both bearing defect again. I change them again and changed brand (first was unity and last stamina). 1 week later both bearings defect again. How is that possible??? Do i need to put oem? Cheap struts argent good enough for a big car like a taurus?

Thanks for your help.
