Toyota didn’t make it easy to remove the factory upper arm frame bolts, especially on the 2014-2016 models where it’s almost impossible. We recommend replacing the bolts with new OEM Toyota bolts to simplify the installation process. That way you’re not having to bend, cut and damage the body sheet metal. Many times the factory bolt needs to be cut in half to be removed. We then install the bolt it in the opposite orientation which solves the problem and allows for easy installation and removal.
