Well I had this issue with my car. Needed a new bumper. I guess the shop screwed around with my re-aiming of the headlights a bit much

I touched it a bit and boom. light faces the ground
I am familiar with this issue and all u have to do is get the white part on the screw to slide back in the black at the top of the pic then the aim will operate correctly.

My issue is the white piece seems stripped from to many turns. it will not go forwards or backwards using the screw aim adjuster.

Does anyone have any ideas? or know where I could send for a repair?

 

Put a c clip on the threads to hold or glue nuts to white piece

 

hum interesting.
can u elaborate about glue nuts?

not familiar with a c clip. i will google now

 

I believe they're called E-Clips and they look like this-

 

I'm not sure using a c clip would work. Most things I've read about them just say they hold things in place.
I need to screw the white piece with enough force behind it so it pops in to the black piece at the one end.

Will the c clip grip the threads on the screw?
And allow me to turn it give the white piece a boost from behind?

I wish there was a nut that could clamp on the threads behind the white piece that I could turn to move on in to place

 

The advise he gave u will work if you put the c clip and hold it once the bolt is turned
