how do i aim headlamps in 98 maxima. i got into an accident and when they redid the front end, the didnt aim the lights right.

 

2 8mm bolts (iirc) on backside of assembly per your owner's manual. One aims left/right other up/down.

 

What Chunger said is correct. There are 2 hexagonal shaped black screws that stick out from the back of the headlight unit. The lower one IIRC aims the headlight up/down and the one located on the side of the headlight aims the headlight left/right.
