up, down, left, right, BAH!!!

[Death By Bass]

ok, so, I had a little accident...

anyway, here are the measurements from the ground, to the wheel arch...
with the air bag switch set to "normal" and the after market height controller set to "0" (which I believe makes it stock)

front right: 67cm
front left: 71cm
rear right: 67cm
rear left: 73cm

now, based on this, I have come to the conclusion that the rear right is stuffed.

but, the height controller says that both sides at the rear are at the same height, so I think the sensor is out of whack.

where should I look? actually, I already did look, and attempted to adjust it, with no luck...

thanks!!!
