The steering rack bellows are flexible boots that cover the ends of the rack. They help keep contaminants out and lubricant in as the steering moves from lock to lock. Once a boot tears or splits, dirt and moisture can get into the rack, so replacing damaged bellows is a key part of steering upkeep.
