Not too hard.. Two jacks. So you can lift the mount up and outwards.. Don't forget to remove the big axial nut first.. It pops out.. You can just see the Arm hiding behind the short shaft. It's bolt needs to be removed, before using the second jack. That's the one I broke on the passenger side.. Yank it clear of the rear diff. open it Clean out the grease And put it back in, lock the axial nut before driving..
