Suggestion?

I used that tool to do my springs recently. When you put it on the spring and before you start twisting on the top, turn the tool clockwise to wind it down onto the spring. This will in turn give more compression on the spring. I also found that on some of them I had to give the top of the tool a smack downward to kick the spring free of the keepers. Finally, using a tool with a magnetic tip helped in removing the keepers.
