I've been searching now for about 45 mins and can not for the life of me find any info at all regarding procedure for knocking out the bearing races from the UFM, FF1, & FF2. Heat ? Cold ? Weld and remove ? It looks easy enough on the UFM as peering down the neck I can see the edges of the races. Stick a drift down the hole and knock out gently ? Slide hammer them out ? Just wondering.... and Thank You !
