I guess that's what you disliked about my post?And I didn't have to heat it up or beat the crap out of it to collapse it. One tap with my 4 pound hammer it collapsed. Put groove where the top bolt slides across shaft and your done. It's a 5 minute job.
I'm glad that you explained how you approached it.
At the time I did mine, they recommended using the Cherokee shaft, not the one from the Grand Cherokee.
