These air suspensions are notorious for leaking over time when they get old. Had a buddy replace his globes inside of them with the mechanical suspension because the cost of getting the globes replaced wasn't worth it for him.

I've heard that if you want to keep it get it fixed, otherwise just replace and get rid of the air suspension. What does each one of those go for, like $400+ per side?
