I doubted if I need this tool based on the price. After some torment and silence, I decided to do it anyway. I'm glad I did, these pads fit well. Whether you use a homemade tool, this tool, or a hammer and chisel, one thing is certain: you need to "convince" your seals in place. This tool just makes it a lot easier, and that's exactly what I wanted. The tool is heavy and made to last. Works with Ford 8.8 inch
