My driver side headlight is loose on my 95 4runner. I have no clue why. I've tried to tweak it with the adjuster screws. But it's not making it any better. Anyone else have this problem?

 

Generally, the headlights are held by the two adjuster screws and one spring. Is your spring still connected? Compare to the headlight on the other side.

 

Sometimes, the 4 screws that hold the metal frame will become loose as well. Get a pair of big pliers and roll the part that sticks out on the rear of the headlight holder from at least two sides. Should give you enough purchase.

Otherwise, upsize screws here and rechase threads for that size.
