Have your rear wheel bearings gone out? Why not do an easy upgrade at the same time? These are a high quality drop-in replacement for the stock bearings with both a rubber outer seal (like stock) and inner seal (stock uses a dust seal). Be sure to pick up new hub nuts at the same time, it's not worth the risk of reusing the old nut. Sold individually, one needed per side, two needed for the entire car (front bearings are different).
