i'm pulling my hair on this one...
i need to drill different tapers into my mk3 spindles for the screw in balljoints i'm going to be running. when i went to pull the spindle/hub/brake assembly apart i don't see how the hub comes apart.. there appears to be a dust cap on the back side, but i haven't been able to remove it.
i've searched some mk3 supra forums with no luck, and the online autozone manual shows a setup similiar to a pickup spindle with a nut

anyone have an idea?? i can post pics if needed. thanks!
