Was trying to pull the rear axle shafts on a 1990 Mitsubishi Montero. Removed the 4 bolts holding it to the axle housing and proceeded to attach my semi home made puller to the hub. I had a harbor freight blind hole bearing puller as my only slide hammer. I attached it to the hub with a piece of angle iron with 3 holes in it. Two hole on the outside for wheel studs across from each other to go through and on in the center to attach the 3lb slide hammer. After an hour of beating on it and it not budging I gave up. Even tried heating the housing a bit with propane torch. Any suggestions on what exactly I should get to do this right?
