It does not seem easy at all.
The adjustment screws are on the back of the headlight assembly. The repair manual seems to require you to remove the grille, the entire light assembly (turnsignal and all and including the bodycolor plastic filler under the light) and then adjust the lights, put them back on, check the alignment, take them off, adjust them again, and keep doing this until they are correct, and then re install grille. Of course this all involves the now standard fragile plastic claws in addition to normal fasteners, and requires prying, etc, without managing to scuff or damage anything.
I get lots of flashes from other drivers too, particularly when the cargo area is heavily laden and the beams are higher.
The left/right ("B") adjustment screws are on the outside top back of the lamp assemblies, and the up/down ("A") ones are on the inside bottom back. Luckily they are not completly inaccessaible (but as close to completely inaccessable as possible). THey are barely visible looking down in behind the lamp housing, but it does not seem humanly possilbe to get an 8mm wrench in there at all.
I have been thinking of drilling a hole in the metal which blocks access to this "A" adjustment screw so a socket could be gotten in there to adjust the aim of the headlights without removing them.
I hope I am wrong and there is some way around all this besides taking it to the shop.
