Headlight Noise/knocking

[Johnny5]

So i went to start up the Z to let it run for a little since I haven't driven it in 3 months and when I turn the headlights on than off I hear a knocking coming from the pop up headlights. The headlights turn on and off and rotate properly but when they close I hear a knocking sound? Anyone have this issue or know what the problem is?

Sounds like the gears are on the way out.

Common C4 issue. Time to replace the 3 plactic bushing cushions in the hub of big drive gear. Plenty of how to articles on the Internet.

Gears for sure I replaced mine with updated metal ones.

So i read on corvette forums, guy had same issue where the headlights rotated fine but made noise and everyone said if it flips open and closed find it was not gears but the metal balls/bearing that need to be replaced, you can find em from ford window motors. When the salt clears i will take them apart and imvestigate.

Hey LI Sounds, i bought my gf that headunit for V Day so i will recommend your shop for install.

Like Phil said, it is the 3 plastic bushings that turn to dust. Three needed per side and you are correct, they are labeled for Ford window assembly in the specialty section of Advance Auto. Costs about $6 dollars. This is all you will need.

You will have to open it and have it all apart anyway. I would do the gears instead of doing it twice just swap the gears as well just 50 bucks. What happens if you take it apart and the gears are shot as well?
