I have been trying to replace my front axle u-joint on the drivers side. i have a 1992 cherokee laredo w\abs brakes  no disconnects i have gotten the axle nut off easy but when i tried to get the axle bearing nuts off they are striped and wont come off any ideas oh and the wheel rotor wont come off either ? if i use a air hammer to remove the nuts on the axle bearing will that take them both off??? i beleive i need to replace the wheel bearing any way ? any idea would be great ! I don't have a torch ! i have  a propane torch i tried to use it to heat everything up but it doesn't do any good  thanks love the site
