I have a 1980 300D. The steering wheel is loose on the grip of the wheel. When you grip it it will twist a little. It's only on the top part of the wheel. I have be thinking of taking injecting some glue into it with a small needle otherwise I could buy another steering wheel, which I don't really want to do. Has anyone else had this problem and does anyone have some advice?

Well... I would try a junk yard and look for a replacement wheel.
