I believe I saw a post from @daveracer years ago about this tool and bought it, but never got around to using it. I tested this out this weekend and it is a VERY good tool to have around.
This would be for the B14, or other models that do not have a flat side to get a wrench on, I'm assuming? Care to share where you got it or what manufacturer/model this tool is?
The B13 inner tie rods have 4 flat sides, normally, unless you've gotten hold of some funky aftermarket one that is round. If you have round ones, then this is what you need.
For $30, might just be something to keep in the toolbox for future use.
