One of the rear wheel bearings on my 1985 W123 Coupe has a little wiggle in it. I got a special tool to remove the nut that clamps up the bearing assembly. Using a two foot breaker bar the nut would not budge. (Yes, I was turning the correct direction.) I put a pipe over the breaker bar and tried again. It broke the tool and the nut did not move.
Have you seen it this tight on other cars? Is there any thing that I can do to get the nut loosened?
Thanks
