I've been running my 4runner as is for years now. I should have addressed this some time ago, but there I am now...
I'm not 100% sure what I'm looking at, but it appears the previous owner replaced the air shock system with a conversion of some sort. As it sits, the springs are compressed enough that when I ride over a speed bump (at low speed) it bottoms out. I'm not sure how safe that would be at high speed. I'm trying to decide how to proceed - update the springs or go back to the air bags.
Anyway, I've got replacement air bags, but don't know if the pump works and I don't know if the ride hight sensors work.
Could I get your thoughts and confirmation of what I think I'm looking at here?
Is this a photo of the air pump? It doesn't look like the ones I see as replacements online.
