the homemade one didn’t save me much money and I had to special order the 3” close nipple (the plumbing equivalent of the electrical conduit bit) so I basically wound up buying that same bearing press kit. it worked great for removing the bearing from the trailing arm.
For getting the outer race off of the hub I used a cheap bearing puller from harbor freight and a straight arm puller (just needed 2 arms) the key thing in my case was that the axle nut washer is exactly the right size (and quite thick) so I used that to hold the tool I drove the bhub out with and then inside that went a centering tool from a press kit so i had something to pull against.
The opening had a bit of rust in and around it. I cleaned it carefully with a brass brush and then 1200 grit, then polished.
After the cleanup:
What the stack looked like to pull off the race. Really glad that washer fit perfectly.
