Good Day All!!

So I am trying to figure out the title issue and getting nowhere fast... So, short of going crazy over it, I figured I would look into the DVD for the NAV. I pulled it apart and could not confirm what the problem was. So, I hooked it back up and just listened to it. I popped the cover off and took a closer look as it was trying to read the DVD I just put in the unit. The noise was isolate nearly perfectly center of the unit that was not associated with the disc spinning... This is what I found when I pulled it apart the second time..... Unfortunately, I have not figured out how to correct the issue...

This is the laser drive... (Without the broken plastic part)



This is how the plastic part sits (without the drive screw in place)...



These are the two parts that work great together when both are complete. Since the black plastic is broken, it doesn't supply enough grip on the drive screw...



So, how do I get the screw drive move the laser assy without the plastic piece that is obviously not cutting it?? I was thinking about wrapping the screw drive with threads of 550 cord and putting them through the arm of the laser assy... But I don't think I could get it tight enough to make a difference without distorting the screw shaft...

Anyone?!!?

OH, I'm guessing this is a common problem?! If I figure out the fix, that would be super great for those than can fix their own instead of buying one for a considerable amount....

Cheers!!
