I'm in the process of getting my rear end cleaned up and installing new seals and bearings so I figured I would take some time and document my process. A press is almost a must have and my HF 12 ton has paid for itself and then some. Well worth the money imho. 1. Here is the old assembly (L and R are same procedure, only difference is the adjuster) 2. Get a cutoff tool and cut a slit in the collar. You will also cut into the bearing, no biggie as it is being replaced. The collar and bearing have to come off to replace the outer seal. 3. Get a cold chisel, gloves and eye pro and start chiseling into the slit. Obviously use a vise or anvil under it. It doesn't take hulk like hammering. The collar will stretch and slide off. You do not need to cut all the way through. 4. Now, what I do is cut a groove in the bearing shoulder and cut off as much of the cage as I can. With the groove I can pull the bearings out with a magnet. When all the bearings are out I pull out and snip the cage in half and remove.
