As indicated earlier I recently replaced the entire steering lock on my 300 TD. I did not have to remove the steering wheel. The key was stuck in the #1 position. I used a Drimel tool and cut the three bolts at the hump which held the wiring harness plug. Once this was safely removed I was able to turn the key to the number #2 position, insert a paper clip wire into the release hole and remove the collar and tumbler mechanism. The hardest part for me was removing the complete steering lock because I over looked the small release pin which needed to be pressed to allow the assembly to be removed from the steering column.

On another project I had to remove a steering wheel and I worked and worked and worked to remove the bolt. Finally I went to a friends house who had an air compressor. I used his impact wrench and removed the bolt with one brief pull of the trigger...
