If you're using the U-bolt clamp to mount the column to the foot box, don't over-tighten the clamp. If you do the column will squeeze and the shaft will not spin freely.

When I did mine, I thought the problem was heat from the headers causing the bushing to expand so I made a heat shield but it didn't help.

I called IDIDIT and they sent me a bushing with a few thousandths of an inch more clearance but that also didn't solve the problem. I then tried loosening the clamp and that was the cure.
