Steering Boots and Gaskets: The Rubber That Keeps Salt Out of the Rack

The steering rack’s inner tie rod ball joint and the moving rack section have to be sealed against road dirt and water. A rubber gaiter (boot) covers each end of the rack, with a smaller gaiter around each outer track rod end joint. When a gaiter splits — usually from age, sometimes from physical damage — water and salt reach inside and corrode the rack’s internal mechanism.

Why timely replacement matters

A split rack gaiter is an MOT advisory. More importantly, it allows progressive damage to the rack. A rack with a long-split gaiter has accumulated months or years of road grit on its internal teeth and the inner ball joint — once internal damage starts, the rack itself needs replacement at far greater cost than the gaiter.

Replacement

Gaiter replacement is straightforward but requires removing the track rod end on one side to slide the new gaiter on. Track rod end inspection at the same service makes sense — they often need replacement anyway.
