Review: Necessary tool - Worked great and the hinge pin is installed with loctite and therefore hard to remove, you also should add a little heat at the housing, but I don’t think you will be able to get it out without the tool, Well worth the money
Review: Extremely poor quality - Not hardened metal. Striped out on first use.
