Some moron aimed the headlights on a 99 Legacy wagon of my acquaintance so that they converge about 50 ft in front of the car, on the ground... and I'm trying to rectify this situation...
On inspection, I find that the owner's manual doesn't appear to have a headlight aiming section, and online searches reveal only that the mechanism is complex. It appears to be a feat of marvelous Japanese engineering (yes, that's sardonic in this particular case) involving between the frame and the glass/housing of each lamp a
- post outboard (towards the side of the car from lamp centerline) and above lamp centerline - a pivot point ?
- adjustor outboard and below centerline
- adjustor inboard (towards car center from lamp centerline) and above lamp centerline
- spring tensioner pulling frame and housing together inboard and at lamp centerline in the vertical plane
so it's not just a simple elevation/windage system. Apart from the fact that some genius of design decided to put plastic hex nuts on a star shaft on the end of adjustors that aren't made of stainless and hence now completely rusted (resulting in the plastic hex nuts stripping off the star when a socket was applied, even after convincing the adjustor shaft directly to turn by gentle application of liquid wrench and a vice-grip) it isn't really crystalline which of the two adjustors per lamp to move to get horizontal and vertical traverse.
I'll eventually head over to an auto parts store and borrow a subaru shop manual for a few minutes, but maybe someone here can clue me in faster ?
TIA,
