2012 JKUR with 44k. I knew my factory bearings blew after 30km to 35 seconds. On the last alignment, I had a -1.2 camber on the driver's side. Switched to these bearings and the collapse problem is gone. I gave 4 stars because the factory sensor and speed sensor didn't fit, I had to use the sensor that came with the stock which is fine but this means it can be difficult to find a replacement sensor on the road to find.
