Product review (5 stars): Peace and Quiet Again!
As many other people have said, it takes some lubrication and muscle to remove the old bearings - but it can be done! It is well worth the savings and the peace and quiet! Nobody mentioned that it was quite difficult to install the new ones, too. Especially when you cannot hit the center of the bearing. I found it easiest to place the old bearing on top of the new one and hammer around the outer edges of the old bearing. This got the new bearing in more efficiently and without the risk of hitting the center of it.
