I ordered Timken for my 2011 Tahoe LT off of Sixity auto. Different bearing depth with small built in seal versus stock bearing with separate stock seal. Im
Sending these back and going back with the stock arrangement. 220K mile preventive maintenance. Replacing tone rings while im in there.
Factory bearings are Timken or Koyo. What you are seeing is a repair bearing and seal unit used when the wear surface of the axle shaft is damaged. They move the bearing to a new position.
I have to replace my rear axle seals on both sides. I was advised to replace the bearings too b/c I am going through the initial trouble. How easy/hard was it to remove the bearings as well? Anyone who views this please assist. I am trying to find a video of someone replacing the seal and bearing but I am only finding reference to the Silverado. I don't know if they are the same or not. Plus, did you lube the bearings and seal before your install and what did you use?

With the right tools it's easy. With the wrong tools you'll wreck the tone rings at the least.
The J-45857 and slide hammer is the best way to get these parts out without damaging the other. I also bought the Performance Tool W89326 and coupled with a commercial slide hammer set pulled the bearings but ruined the tone rings. It barely fit but it did the job.
The inside diameter of the axle tube is graduated so that you cannot put the tone rings in too deep. I used the J-45860 but you could get by with a large socket. Same with the J-23690. The seals could be installed with a 2x4 or very light taps of a hammer. I've done it both ways over the years.
You can save a lot of money by buying the parts in the AAM brand, the people that made the axle. 74050013 -
The axle tubes are the same for all of the GMT900 1500s. So yes, videos of Yukons, Sierras, Silverados, all the same.
