Once again I have to replace the strut mounts on my 1997 Jetta. I am not impressed with the stock replacements and have purchased polyurethane mounts. The question is upgraded pivot bearings. Stock bearings are...... Less than good and have a short life. And the bearings amount to small cups with a number loose bearings rolling around inside of them. So, what do I need to know to find a bearing that will fit and live at the top of a strut?
