Parts for your 2012 Toyota Fortuner-Rack boots

2012 Toyota Fortuner rack boots — what they do and when to replace them

Based on Toyota’s workshop literature for the AN60-series Fortuner (Steering section) and the Toyota Electronic Parts Catalogue (Steering Gear & Linkage diagram), the 2012 Toyota Fortuner uses a power-assisted rack-and-pinion steering gear that is fitted with rack boots (also called steering rack bellows or gaiters) on both sides of the rack. So yes — rack boots are relevant to, and used on, the 2012 Fortuner.

On a 2012 Fortuner, the rack boots are the flexible bellows that seal each end of the steering rack where the inner tie rods join. Their day job is simple but critical: keep dust, water, and grit away from the polished rack bar and inner tie rod joints, and hold a smear of grease where it’s needed. They also act as a tell-tale — if power steering fluid starts pooling inside a boot, it often points to a leaking inner rack seal.

For everyday servicing, a quick glance at the boots pays off. Look for cracks, splits, oiliness, or loose clamps. If the boot is torn, road grime can quickly chew out the inner joint and the rack bar, turning a small, cheap part into a big steering-gear bill. If there’s fluid inside the boot or wetness around the clamps, have the rack assessed before simply fitting a new boot.

• Symptoms of a failing rack boot: visible splits or perishing, grease flung onto the control arm, damp/oily patches around the boot, grit inside the bellows, or a clicking/knocking when turning if the inner joint has been contaminated.
• Good practice at service time: inspect both boots on the hoist, clean with mild detergent only, and replace single-use metal bands with new clamps if they’re loose or corroded.

When replacing, the outer tie rod end is usually removed from the knuckle, the old clamps are cut, and the boot is slid off. It’s a great chance to check inner tie rod play. Fit the new boot in the correct orientation, seat it fully in the rack groove, and secure with quality clamps. Because the tie rod end comes off, the toe setting can shift — a wheel alignment is strongly recommended straight after. Avoid cheap, thin boots, OE or high-quality aftermarket bellows last longer against Aussie and Kiwi heat, UV, and off-road spray.

Look after the rack boots and the Fortuner’s steering stays tight, quiet, and predictable for many kilometres.

Popular questions about 2012 Toyota Fortuner rack boots

How long do rack boots typically last on a Fortuner?
In normal on-road use, quality rack boots can last many years and well over 100,000 km. Vehicles that see off-road work, corrugations, or creek crossings should have the boots checked more often, as heat, UV, and debris accelerate ageing.

Do I need a wheel alignment after replacing rack boots?
Yes, it’s best practice. Removing the tie rod end to slide the boot off can nudge the toe setting. A post-job alignment ensures the Fortuner tracks straight and avoids uneven tyre wear.

What are the signs a rack boot needs replacing?
Cracks, splits, loose or rusty clamps, grease sling on nearby suspension parts, or any wet, oily look around the boot. Grit inside the bellows or fluid pooling in the boot are red flags that need prompt attention.
