This may have been covered before(?)... if so, I missed it. Leave the SST(never needed it) and press in storage. Go place the race in the freezer. Go knock out the old outer race. Go get your new colder race(s). Lightly heat the ball knuckle area with a propane torch, I did it for maybe 15 seconds and it below freezing out right now. Drop the race in, and I do mean drop, it slides in there with no effort. The cool race sucks the heat from the knuckle and in a few seconds, it is tightly set in place. Repeat, enjoy.
