Thanks for the help.

Who is it easy for, DIY types like me, or for MBZ mechanics? Not sure what you mean. I've been turning wrenches for years, including on my Porsche, but I only own the normal hand tools.

Is access to these bushings from the top? Can I get access by removing the knob and lifting the gate's black cover?

Does the knob screw off, or do I need to pop off the cap to find an access bolt? How about the cover? I hate to experiment with cosmetic items.

Thanks again,
Bob
