3. Insert floor jack under handle of breaker bar so that when you begin lifting, it will force the plug counter clockwise.

4. Keep going even when it seems it will lift the car off the ramps, it will "POP!" free.

This has worked on all 3 of our MB's that I have worked on. On mine it raised the car a good 8-10 inches on the suspension before there was enough force to break it loose.

Heating the diff around the plug should help too...expands the metal.

Good luck!
