Combines M rear axle

all crop, If you have a arc welder or wrie welder you should be able to get them out. Turn the amperage down so you can run a bead on the inside of needle bearing housing.You may have to move rod quickly so you don't burn through.This should shrink housing allowing you to tap out with long punch and hammer.May have to weld several short beads if it is real tight. Good luck, Hyper Harvest II

my theory-if all else fails get the blue wrench.you can bust the needles out and peel the old bearing housing out with a torch,going quickly so you don't burn into the spindle housing[should not be a problem with bearing housing being so thin].best of luck.
