Liquid wrench, propane torch, a 4 lb hammer and three different lengths of 1/2" bolts as drifts.
The left came our fairly easily. Just got hung on the bushing. Out came the torch for about 20 minutes and that was done. At one point I did hammer the pin back and grind down the mushroomed section, thinking that it might start to be a problem.
The right was more challenging. I actually started there, but the pin would only budge about 1/2". Soaked it in liquid wrench and moved to the other side.
My theory was that the spindle pin was deformed by the locking pin, making it difficult to slide out. So I heated the strut on the side that the deformed section of pin would be sliding through. Then another liberal dose of liquid wrench and hammer, hammer, hammer.
I'm guessing that it took a total of about 100-150 hammer blows to remove each pin. And that last one shot it out about 8 feet.
