I did mine a few months ago and used my motorcycle crankshaft puller that I use to install crankshafts into engines. Doesn't work perfectly as the tube doesn't seat perfectly against the control arm and I had to use some square steel stock to space it away and rest on the tube of the control arm squarely. Just thought I would let people know that this tool does work and is available as there isn't a specific tool readily available.
