I had this same problem. Of course the shope said I did it, except they were only ones to change oil. Needless to say I bought a lift and did it myself. I used all the tricks oincludeing those m the previous discussion (3-4-6 months ago??). grinded wrenches, chisel, lubricant, heat, etc. I finally hooked up my air chisel and hit it twice and it poped loose. Reinstalled 14 mm
