1989 300SE.

I was trying to correct the aim of the left headlight using the height adjuster. I had previously adjusted it a little too high. As I was turning the knob it got very stiff then it felt like something snapped and the headlight aim suddenly dropped so it was pointing at the ground very close to the front of the car. The adjustment knob now turns very freely, and no longer does anything. Is there anything I can do temporarily to bring it up until I can get the parts to fix it right?

What broke exactly and what part do I need to fix it?

Also, I've had a very hard time trying to aim the headlights on this car. It seems like the adjusters, especially the one that controls the left/right movement does little or nothing and I'm afraid it will snap if I keep trying. Does anyone know which way I should turn each knob to make the function go in the right direction. The CD doesn't really say anything, nor does the owner's manual. I've done a search of the archives but there's little information on adjusting.

Should I lubricate the adjusters so I don't break them again? If so with what and where should it be applied.

Both sides have new Bosch lenses and frames. Does anyone have a good bucket for sale at a decent price.
