Kind of feel like I cheated. Using the provided tool and a light hammer, the old bushings came right out. Tool fit perfectly and didn't need pounded back out from the other end like some of the cheaper options.
The new bushings fit great too. Just enough snugness to retain them when removing the doors but not enough to have to work putting them in.
Also unlike some cheaper brands, these bushings weren't obviously made of ABS or cast in a mold. They look to be true Delrin, which is a material I see daily at work, and, with some effort, you can visually see the tooling marks from them being machined out.
Excellent product and experience. So happy that we chose to go with TMR Customs for the replacement bushings on Tinker Toy and will definitely be picking up a second set for my other Jeep.
