On my '99 Legacy 2.5GT wagon, I lubricated the adjuster screws and put an 8mm wrench on the little plastic adjusters. It took a couple of seconds before I discovered that the little plastic caps were just spinning around. In fact one of the four caps had fallen off before I ever got to it.
When I pulled the caps off (it didn't take any effort), the steel screws that were left have no heads or flats or anything that will let you turn them. In fact the didn't seem to have anything for the plastic caps to grip the shafts at all.
When I tried turning the shafts with a little pair of vise-grips the shafts won't turn at all.
What gives? It looks like the shafts rusted, this knocked the plastic caps loose and made the shafts very difficult to turn.
I can imagine dropping by the dealer and having them tell me that I need
2 new headlight assemblies for $500 each!
What do I do now? I need the headlights to point a little higher.
