Parts for your 2012 Toyota Crown-Rack boots

2012 Toyota Crown rack boots: purpose, care, and when to replace

Based on the Toyota Crown S200/S210 Repair Manual (Steering section) and the Toyota Electronic Parts Catalogue (EPC) for the 2012 model year, the vehicle’s rack-and-pinion steering gear is fitted with bellows-type rack boots (also called steering rack dust boots or gaiters). These sources show the boots as part of the steering gear and link assembly, protecting the inner tie rod joints and rack from grit and moisture. Industry material from JTEKT/Toyota EPS rack suppliers also notes that bellows boots remain necessary on electric and hydraulic rack-and-pinion systems to seal out contaminants and manage internal pressure changes. So, yes—the 2012 Toyota Crown absolutely uses rack boots.

On a 2012 Toyota Crown, rack boots do a deceptively big job. They’re flexible bellows that cover the inner tie rod ends and the exposed sections of the rack bar, keeping water, road grime, and dust out. That means less corrosion, less wear on the inner joints, and a quieter, tighter steering feel over the long haul. If a boot splits, grit and moisture get in quickly, and the inner joints can chew themselves out in no time—often turning a cheap boot into a pricier steering repair.

For servicing, a quick visual under the front of the Crown at every oil change is smart practice. Look for splits, loose or missing clamps, grease seepage, or boots that look collapsed or ballooned. Any tear or failed clamp is a prompt replacement—don’t wait for a shake or clunk at the wheel.

• Replace boots in pairs when practical, both see the same age and conditions.
• Use quality EPDM boots and proper ear-style or band clamps—skip cable ties.
• Clean the rack and inner tie rod area before fitting, don’t over-pack with grease.
• If the Crown has a pressure-equalising passage or tube between boots, keep it clear.
• Set the boot at the correct orientation marks and clamp positions from the workshop manual.
• If inner tie rods are disturbed, torque to spec and get a wheel alignment afterwards.

Typical signs of trouble in a 2012 Toyota Crown are a faint click over bumps, vague on-centre feel, or visible splits after a muddy weekend. Left alone, a torn boot can ruin inner joints and even let water pit the rack. Swapping boots is a tidy, workshop-level job, done right with the correct clamps and alignment check, it keeps the steering tight, quiet, and compliant—just the way a Crown should feel on Aussie and Kiwi roads.

Popular questions about 2012 Toyota Crown rack boots

Do 2012 Toyota Crown models have rack boots even with electric power steering?

They do. Whether the Crown is fitted with hydraulic or electric power steering, it still uses bellows-style rack boots to shield the rack bar and inner tie rod joints from water and grit, and to manage pressure changes as the rack moves.

Is it safe to drive a 2012 Toyota Crown with a torn rack boot?

It’s not recommended. A split boot lets in dirt and moisture, which can quickly wear the inner tie rod joint and corrode the rack. Short trips to a workshop might be okay, but plan immediate replacement to avoid bigger steering repairs.

Do both rack boots need replacing at the same time?

It’s best practice. If one boot has perished, the other is usually not far behind. Replacing both helps maintain even protection and saves on repeat labour, especially if an alignment is needed after work on tie rods.
