When people say they use a puck, are they saying they cut it like this video, or are they just putting the puck on the jack/stand and then lifting on the pinch weld with the puck? Why is that supposedly better than just using the jack? Unless you're jacking wildly or dropping the Jeep to quickly, it shouldn't really matter what material is jacking the weld, right?
I'm thinking I'll just cut my own pinch weld jack pad out of a 2x4 and call it a day... The only hockey pucks I have were signed by hockey players
