I have to admit to not knowing exactly how the Jeep column is designed and how it collapses, however I cannot see how you can damage the assembly with a puller. You can destroy the wheel of course but I can't see how you can put force on the shaft to collapse it. If the wheel won't pull off the spline there is nothing fixed to allow the puller to exert downward force on the shaft all it can do is destroy the puller itself. The only way you could have buggered the shaft is by belting the crap out of it.
