I just got through doing this to mine and it works. Remove the bolt completely like you did and shove the shaft that goes to the firewall in and out about 15 times. You might have to force it out of the link that it is attached to from being together for so long but mine just slipped out with no porb. Remember, it's the part that is closest to the firewall that you move in and out. Just don't turn the shaft. Keep it in the position. Just move it completely in and out about 15 times. Guaranteed it will fix the clunking problem that i've have for about 2 years!
