It was pretty easy. The toughest part for me was figuring out which way the screw turned. Opposite of a normal screw by the way. So for a while I was tightening it instead of taking it out. After that the insert itself is a pretty tight fit so you really have to jam it in there. Then I just screwed it in and the washer helped press it into place.
So far I've noticed wheel hop is non existent and gear changes are a little firmer. It's been great so far with barley any increased vibration (some on start up, in reverse and low rpm). One of the best mods you can do.
