Why? Just wondering. I am certainly not a mechanic by anyone's estimation. I assume you are worried about breaking the C-clamp press part or is there something else I am missing. I have understood from what I've read is it's actually better to use an impact. (again just a shadetree guy here so not claiming to know too much). A ratchet or breaker tends to want to rotate the whole thing. That concerned me that it would spin the entire lot off using a breaker when torque got up there. The impact seems alot safer as I went. I am also not sure i'd have ever gotten enough torque on it without the impact. I'm all ears to learn though and appreciate any advice I can get.
